Use Existing Chrome Browser with remote-debugging-port using RobotFramework - selenium-webdriver

I am trying to use existing google chrome instance using RobotFramework (SeleniumLibrary). I am starting the chrome instance like this
chrome.exe --remote-debugging-port=9289 --user-data-dir="D:\gcdata"
This my code in robotframework
${options}= Evaluat sys.modules['selenium.webdriver'].ChromeOptions() sys,selenium.webdriver
${prefs}= Create Dictionary debuggerAddress 127.0.0.1:9289
Call Method ${options} add_experimental_option prefs ${prefs}
Create WebDriver Chrome chrome_options=${options}
When I run the RobotFramework code, it invokes a new browser. Can anyone help me here telling what is going wrong and how to fix it.

Using the most recent versions of the Python Selenium Module, Chrome and ChromeDriver the following Robot script will connect to an already running chrome that is started using:
chrome.exe --remote-debugging-port=9289 --user-data-dir="C:\temp\gdata"
chrome_debugger.robot
*** Settings ***
Library SeleniumLibrary
Library Collections
*** Test Cases ***
TC
${ChromeOptions}= Evaluate sys.modules['selenium.webdriver'].ChromeOptions() sys,selenium.webdriver
# Method debugger_address is not callable so convert to Capabilities Dictionary and set it manually
${ChromeCapabilities}= Call Method ${ChromeOptions} to_capabilities
Set To Dictionary ${ChromeCapabilities["goog:chromeOptions"]} debuggerAddress 127.0.0.1:9289
# Instead of using the Chrome Options use Capabilities.
Create WebDriver Chrome desired_capabilities=${ChromeCapabilities}
Go To http://cnn.com
Even though the ChromeOptions class (GitHub) has the debugger_address(self, value) method, calling this method from Robot Framework returns an error. Therefore converting the ChromeOptions class to a Capabilities dictionary and adding it manualy to the dictionary before passing it to the webdriver through the desired_capabilities argument.

I tried to invoke chrome from selenium. The browser is getting open but no data is loaded [duplicate]

I am trying to launch chrome with an URL, the browser launches and it does nothing after that.
I am seeing the below error after 1 minute:
Unable to open browser with url: 'https://www.google.com' (Root cause: org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist
(Driver info: chromedriver=2.39.562718 (9a2698cba08cf5a471a29d30c8b3e12becabb0e9),platform=Windows NT 10.0.15063 x86_64) (WARNING: The server did not provide any stacktrace information)
My configuration:
Chrome : 66
ChromeBrowser : 2.39.56
P.S everything works fine in Firefox
Thumb rule
A common cause for Chrome to crash during startup is running Chrome as root user (administrator) on Linux. While it is possible to work around this issue by passing --no-sandbox flag when creating your WebDriver session, such a configuration is unsupported and highly discouraged. You need to configure your environment to run Chrome as a regular user instead.
This error message...
org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist
...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Your code trials and the versioning information of all the binaries would have given us some hint about what's going wrong.
However as per Add --disable-dev-shm-usage to default launch flags seems adding the argument --disable-dev-shm-usage will temporary solve the issue.
If you desire to initiate/span a new Chrome Browser session you can use the following solution:
System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized"); // open Browser in maximized mode
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model
WebDriver driver = new ChromeDriver(options);
driver.get("https://google.com");
disable-dev-shm-usage
As per base_switches.cc disable-dev-shm-usage seems to be valid only on Linux OS:
#if defined(OS_LINUX) && !defined(OS_CHROMEOS)
// The /dev/shm partition is too small in certain VM environments, causing
// Chrome to fail or crash (see http://crbug.com/715363). Use this flag to
// work-around this issue (a temporary directory will always be used to create
// anonymous shared memory files).
const char kDisableDevShmUsage[] = "disable-dev-shm-usage";
#endif
In the discussion Add an option to use /tmp instead of /dev/shm David mentions:
I think it would depend on how are /dev/shm and /tmp mounted.
If they are both mounted as tmpfs I'm assuming there won't be any difference.
if for some reason /tmp is not mapped as tmpfs (and I think is mapped as tmpfs by default by systemd), chrome shared memory management always maps files into memory when creating an anonymous shared files, so even in that case shouldn't be much difference. I guess you could force telemetry tests with the flag enabled and see how it goes.
As for why not use by default, it was a pushed back by the shared memory team, I guess it makes sense it should be useing /dev/shm for shared memory by default.
Ultimately all this should be moving to use memfd_create, but I don't think that's going to happen any time soon, since it will require refactoring Chrome memory management significantly.

Outro
Here is the link to the Sandbox story.
I started seeing this problem on Monday 2018-06-04. Our tests run each weekday. It appears that the only thing that changed was the google-chrome version (which had been updated to current) JVM and Selenium were recent versions on Linux box ( Java 1.8.0_151, selenium 3.12.0, google-chrome 67.0.3396.62, and xvfb-run).
Specifically adding the arguments "--no-sandbox" and "--disable-dev-shm-usage" stopped the error.
I'll look into these issues to find more info about the effect, and other questions as in what triggered google-chrome to update.
ChromeOptions options = new ChromeOptions();
...
options.addArguments("--no-sandbox");
options.addArguments("--disable-dev-shm-usage");
We were having the same issues on our jenkins slaves (linux machine) and tried all the options above.
The only thing helped is setting the argument
chrome_options.add_argument('--headless')
But when we investigated further, noticed that XVFB screen doesn't started property and thats causing this error. After we fix XVFB screen, it resolved the issue.
I had the same problem in python. The above helped. Here is what I used in python -
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome('/path/to/your_chrome_driver_dir/chromedriver',chrome_options=chrome_options)
I was facing the same issue recently and after some trial and error it worked for me as well.

options.addArguments("--no-sandbox"); //has to be the very first option

In my case in the following environment:
Windows 10
Python 3.7.5
Google Chrome version 80 and corresponding ChromeDriver in the path C:\Windows
selenium 3.141.0
I needed to add the arguments --no-sandbox and --remote-debugging-port=9222 to the ChromeOptions object and run the code as administrator user by lunching the Powershell/cmd as administrator.
Here is the related piece of code:
options = webdriver.ChromeOptions()
options.add_argument('headless')
options.add_argument('--disable-infobars')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--no-sandbox')
options.add_argument('--remote-debugging-port=9222')
driver = webdriver.Chrome(options=options)
I ran into this problem on Ubuntu 20 with Python Selenium after first downloading the chromedriver separately and then using sudo apt install chromium-browser Even though they were the same version this kept happening.
My fix was to use the provided chrome driver that came with the repo package located at
/snap/bin/chromium.chromedriver
driver = webdriver.Chrome(chrome_options=options, executable_path='/snap/bin/chromium.chromedriver')
Update:
I am able to get through the issue and now I am able to access the chrome with desired url.
Results of trying the provided solutions:
I tried all the settings as provided above but I was unable to resolve the issue
Explanation regarding the issue:
As per my observation DevToolsActivePort file doesn't exist is caused when chrome is unable to find its reference in scoped_dirXXXXX folder.
Steps taken to solve the issue
I have killed all the chrome processes and chrome driver processes.
Added the below code to invoke the chrome
System.setProperty("webdriver.chrome.driver","pathto\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(options);
driver.get(url);
Using the above steps I was able to resolve the issue.
Thanks for your answers.
In my case it was problem with CI Agent account on ubuntu server, I solved this using custom --user-data-dir
chrome_options.add_argument('--user-data-dir=~/.config/google-chrome')
My account used by CI Agent didn't have necessary permissions, what was interesting everything was working on root account
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--profile-directory=Default')
chrome_options.add_argument('--user-data-dir=~/.config/google-chrome')
driver = webdriver.Chrome(options=chrome_options)
url = 'https://www.google.com'
driver.get(url)
get_url = driver.current_url
print(get_url)
There is lot of possible reasons for the RESPONSE InitSession ERROR unknown error: DevToolsActivePort file doesn't exist error message (as we can see from the number of answers for this question). So let's dive deeper to explain what exactly this error message means.
According to chromedriver source code the message is created in ParseDevToolsActivePortFile method. This method is called from the loop after launching chrome process.
In the loop the driver check if the chrome process is still running and if the ParseDevToolsActivePortFile file was already created by chrome. There is a hardcoded 60s timeout for this loop.
I see two possible reasons for this message:
Chrome is really slow during startup - for example due to lack of system resources - mainly CPU or memory. In this case it can happen that sometimes chrome manage to start in time limit and sometimes not.
There is another issue which prevents chrome to start - missing or broken dependency, wrong configuration etc. In such case this error message is not really helpful and you should find another log message which explain the true reason of the failure.
It happens when chromedriver fails to figure out what debugging port chrome is using.
One possible cause is an open defect with HKEY_CURRENT_USER\Software\Policies\Google\Chrome\UserDataDir
But in my last case, it was some other unidentified cause.
Fortunately setting port number manually worked:
final String[] args = { "--remote-debugging-port=9222" };
options.addArguments(args);
WebDriver driver = new ChromeDriver(options);
As stated in this other answer:
This error message... implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Among the possible causes, I would like to mention the fact that, in case you are running an headless Chromium via Xvfb, you might need to export the DISPLAY variable: in my case, I had in place (as recommended) the --disable-dev-shm-usage and --no-sandbox options, everything was running fine, but in a new installation running the latest (at the time of writing) Ubuntu 18.04 this error started to occurr, and the only possible fix was to execute an export DISPLAY=":20" (having previously started Xvfb with Xvfb :20&).
You can get this error simply for passing bad arguments to Chrome. For example, if I pass "headless" as an arg to the C# ChromeDriver, it fires up great. If I make a mistake and use the wrong syntax, "--headless", I get the DevToolsActivePort file doesn't exist error.
I was stuck on this for a very long time and finally fixed it by adding this an additional option:
options.addArguments("--crash-dumps-dir=/tmp")
I know it's an old question and it already has a lot of answers. However, I ran into this issue, bumped into this thread and none of the proposed solutions helped. After spending a few days(!) on it I finally found a solution:
My problem was that I was using the selenium/standalone-chrome image on a MacBook with M1 chip. After switching to seleniarm/standalone-chromium everything finally started to work.
I had the same issue, but in my case chrome previously was installed in user temp folder, after that was reinstalled to Program files. So any of solution provided here was not help me. But if provide path to chrome.exe all works:
chromeOptions.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
I hope this helps someone =)
In my case it happened when I've tried to use my default user profile:
...
options.addArguments("user-data-dir=D:\\MyHomeDirectory\\Google\\Chrome\\User Data");
...
This triggered chrome to reuse processes already running in background, in such a way, that process started by chromedriver.exe was simply ended.
Resolution: kill all chrome.exe processes running in background.
update capabilities in conf.js as
exports.config = {
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['todo-spec.js'],
capabilities: {
browserName: 'chrome',
chromeOptions: {
args: ['--disable-gpu', '--no-sandbox', '--disable-extensions', '--disable-dev-shm-usage']
}
},
};
Old question but a similar issue nearly drove me to insanity so sharing my solution. None of the other suggestions fixed my issue.
When I updated my Docker image Chrome installation from an old version to Chrome 86, I got this error. My setup was not identical but we were instantiating Chrome through a selenium webdriver.
The solution was to pass the options as goog:chromeOptions hash instead of chromeOptions hash. I truly don't know if this was a Selenium, Chrome, Chromedriver, or some other update, but maybe some poor soul will find solace in this answer in the future.
For Ubuntu 20 it did help me to use my systems chromium driver instead of the downloaded one:
# chromium which
/snap/bin/chromium
driver = webdriver.Chrome('/snap/bin/chromium.chromedriver',
options=chrome_options)
And for the downloaded webdriver looks like it needs the remote debug port --remote-debugging-port=9222 to be set, as in one of the answers (by Soheil Pourbafrani):
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--remote-debugging-port=9222")
driver = webdriver.Chrome('<path_to>/chromedriver', options=chrome_options)
Date 9/16/2021
Everything works fine running chrome with selenium locally with python inside the docker hosted ubuntu container. When attempting to run from Jenkins the error above is returned WebDriverException: unknown error: DevToolsActivePort
Environment:
-Ubuntu21.04 inside a docker container with RDP access.
-chromedriver for chrome version: 93
Solution:
Inside the python file that starts the browser I had to set the DISPLAY environment variable using the following lines:
import os
os.environ['DISPLAY'] = ':10.0'
#DISPLAY_VAR = os.environ.get('DISPLAY')
#print("DISPLAY_VAR:", DISPLAY_VAR)
In my case, I was trying to create a runnable jar on Windows OS with chrome browser and want to run the same on headless mode in unix box with CentOs on it. And I was pointing my binary to a driver that I have downloaded and packaged with my suite. For me, this issue continue to occur irrespective of adding the below:
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--no-sandbox");
System.setProperty("webdriver.chrome.args", "--disable-logging");
System.setProperty("webdriver.chrome.silentOutput", "true");
options.setBinary("/pointing/downloaded/driver/path/in/automationsuite");
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("window-size=1024,768"); // Bypass OS security model
options.addArguments("--log-level=3"); // set log level
options.addArguments("--silent");//
options.setCapability("chrome.verbose", false); //disable logging
driver = new ChromeDriver(options);
Solution that I've tried and worked for me is, download the chrome and its tools on the host VM/Unix box, install and point the binary to this in the automation suite and bingo! It works :)
Download command:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
Install command:
sudo yum install -y ./google-chrome-stable_current_*.rpm
Update suite with below binary path of google-chrome:
options.setBinary("/opt/google/chrome/google-chrome");
And.. it works!
I also faced this issue while integrating with jenkins server, I was used the root user for jenkin job, the issue was fixed when I changed the user to other user. I am not sure why this error occurs for the root user.
Google Chrome Version 71.0
ChromeDriver Version 2.45
CentOS7 Version 1.153
I run selenium tests with Jenkins running on an Ubuntu 18 LTS linux. I had this error until I added the argument 'headless' like this (and some other arguments):
ChromeOptions options = new ChromeOptions();
options.addArguments("headless"); // headless -> no browser window. needed for jenkins
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model
ChromeDriver driver = new ChromeDriver(options);
driver.get("www.google.com");
Had the same issue. I am running the selenium script on Google cloud VM.
options.addArguments("--headless");
The above line resolved my issue. I removed the other optional arguments. I think the rest lines of code mentioned in other answers did not have any effect on resolving the issue on the cloud VM.
in my case, when i changed the google-chrome and chromedriver version, the error was fixed :)
#google-chrome version
[root#localhost ~]# /usr/bin/google-chrome --version
Google Chrome 83.0.4103.106
#chromedriver version
[root#localhost ~]# /usr/local/bin/chromedriver -v
ChromeDriver 83.0.4103.14 (be04594a2b8411758b860104bc0a1033417178be-refs/branch-heads/4103#{#119})
ps: selenium verison was 3.9.1
No solution worked for my. But here is a workaround:
maxcounter=5
for counter in range(maxcounter):
try:
driver = webdriver.Chrome(chrome_options=options,
service_log_path=logfile,
service_args=["--verbose", "--log-path=%s" % logfile])
break
except WebDriverException as e:
print("RETRYING INITIALIZATION OF WEBDRIVER! Error: %s" % str(e))
time.sleep(10)
if counter==maxcounter-1:
raise WebDriverException("Maximum number of selenium-firefox-webdriver-retries exceeded.")
It seems there are many possible causes for this error. In our case, the error happened because we had the following two lines in code:
System.setProperty("webdriver.chrome.driver", chromeDriverPath);
chromeOptions.setBinary(chromeDriverPath);
It's solved by removing the second line.
I ran into same issue, i am using UBUNTU, PYTHON and OPERA browser. in my case the problem was originated because i had an outdated version of operadriver.
Solution:
1. Make sure you install latest opera browser version ( do not use opera beta or opera developer), for that go to the official opera site and download from there the latest opera_stable version.
Install latest opera driver (if you already have an opera driver install, you have to remove it first use sudo rm ...)
wget https://github.com/operasoftware/operachromiumdriver/releases/download/v.80.0.3987.100/operadriver_linux64.zip
unzip operadriver_linux64.zip
sudo mv operadriver /usr/bin/operadriver
sudo chown root:root /usr/bin/operadriver
sudo chmod +x /usr/bin/operadriver
in my case latest was 80.0.3987 as you can see
Additionally i also installed chromedriver (but since i did it before testing, i do not know of this is needed) in order to install chromedriver, follow the steps on previous step :v
Enjoy and thank me!
Sample selenium code
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Opera()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.quit()
I came across the same problem, in my case there are two different common user userA and userB in Linux system.
userA first run the selinium programe which start chrome browswer with ChromeDriver successfully, when it came to userB, the DevToolsActivePort file doesn't exist error occur.
I tried the --remote-debugging-port=9222 option, but it lead to a new exception:
selenium.common.exceptions.WebDriverException: Message: chrome not reachable
The I ran google-chome directory and see the following error:
mkdir /tmp/Crashpad/new: Permission denied (13)
The I search the problem and got this:

How do you configure your Chrome Browser to pass through a proxy in Selenium2Library of Robot Framework?

I've seen the example in Create Webdriver for Firefox proxy. However I don't have any idea on how to implement this on Chrome.
Edited this question to display the version of installed packages in my machine:
ChromeDriver 2.25.426935
Google Chrome Version 56.0.2924.87 (64-bit)
robotframework (3.0)
robotframework-selenium2library (1.8.0)
selenium (3.0.2)
ChromeDriver supports using a predefined proxy as well, but you have to specify it as a command line argument in the ChromeOptions object which you can pass when creating a ChromeDriver. See this answer for how to do it in python for example: https://stackoverflow.com/a/11821751/7433999
When using then Selenium2Library and the Create Webdriver keyword it should be possible to achieve the same, if you construct a chrome_options dictionary in the correct form, and pass it to the keyword.
Something like this could work:
${args}= | Create List | --proxy-server=1.2.3.4:8080
${chrome_options}= | Create Dictionary | args=${args}
Create WebDriver | Chrome | chrome_options=${chrome_options}
To use ChromeOptions in RobotFramework you may want to do something like:
In ./project_root/my_library.py
from typing import Union
from selenium.webdriver.chrome.options import Options
def Get_Proxy_Option(url: str, port: Union[int, str]) -> Options:
options = Options()
options.add_argument(f"--proxy-server={url}:{port}")
return options
In ./project_root/my_testcase.robot
*** Settings ***
Library SeleniumLibrary
Library ./my_library.py
*** Keywords ***
Open Browser With Proxy
[Arguments] ${browser_url} ${proxy_url}=url.to.proxy ${proxy_port}=8080
${options}= Get_Proxy_Options #{ext_paths} url=${proxy_url} port=${proxy_port}
Open Browser ${url} Chrome options=${options}

Launch chrome browser

I am trying to launch chrome browser (version 26.0) using webdriver.
I am getting the following error message.
Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see http://code.google.com/p/selenium/wiki/ChromeDriver.
at com.google.common.base.Preconditions.checkState(Preconditions.java:176)
at org.openqa.selenium.remote.service.DriverService.findExecutable(DriverService.java:105)
at org.openqa.selenium.chrome.ChromeDriverService.createDefaultService(ChromeDriverService.java:69)
at org.openqa.selenium.chrome.ChromeDriver.<init>(ChromeDriver.java:107)
at googleSearch.main(googleSearch.java:13)
Code I used:
driver = new ChromeDriver();
driver.navigate().to("http://www.google.com/");
I use mac 10.8.2.
For this to work, you need to:
Install Chrome
Install Chrome Web Driver
Make sure you have the chrome web driver in you path, for example on Windows something pointing to chromedriver2_win32_0.8. You can put that in your path by either: (a) Modifying your windows path environment variable, or; (b) adding the following to your java command line options:
-Dwebdriver.chrome.driver='/path/to/driver'
In case of using selenium grid
-Dwebdriver.chrome.driver='/path/to/driver'
has to be added while creating a node from command line.
1) In case of using selenium without GRID:
System.setProperty("webdriver.chrome.driver","/absolute/path/to/chromedriver");
driver = new ChromeDriver();
does the job.
2) In case of using selenium with GRID:
System.setProperty("webdriver.chrome.driver","/absolute/path/to/chromedriver");
driver = new ChromeDriver();
And from command line, while creating a node for chrome browser one needs to pass
-Dwebdriver.chrome.driver='/absolute/path/to/chromedriver'
The above two changes did the job for me, apart from this I was getting this libnss3.so not found error which I solved by creating a symlink of libnss3.so present in /usr/lib/x86_64-linux-gnu/ folder to /usr/lib/
ln -s /usr/lib/x86_64-linux-gnu/libnss3.so /usr/lib/libnss3.so
PS: Also make sure that you are using 64bit OR 32bit version of chrome driver as per your system.
For chrome to work with selenium-webdriver you need to have not only a working chrome browser installed, but also the chromedriver executable. Note that these are TWO different executable files that both need to be specified.
change the permission of file and then run your code again.
Open command prompt and navigate to directory where your chrome exe exists and write
chmod 777 filename
Hope it will solve your problem.

Selenium IDE - local (non-webhosted) file access for testing?

My Problem
When Selenium IDE is used to run a test, the "Base URL" is always accessed via http on some web server.
I need to know if (and how) its possible to get Selenium IDE to run a test on a locally stored file. When opening a file in Firefox, the path looks something like this in the Address Bar: file:///C:/Documents and Settings/username/My Documents/somehtml.html
However, Selenium gives a nasty error when I put this path in the Selenium IDE's Base URL field for my test (See bottom of my post).
What I tried
I run Windows XP and have tried switching the file path slashes to backslashes while keeping the protocol (file:///) slashes as is. I tried replacing spaces with %20 too.
I also considered whether my Firefox proxy settings might be causing an issue, but it isn't because if i open the file in Firefox it does so without issue.
The solution I'm working on is to avoid Selenium WebDriver at this phase. I know it is better on a technical but there are practical reasons why I can't use that at this point. Selenium IDE must be used for now.

open about:config then change security.fileuri.strict_origin_policy to false. enjoy
One solution is to use the open command as the first line in your test, and set the local path as the target. This is fine for a handful of tests, but may not be sufficient for larger test suites.
command: open
target: file///c:/path/to/your/file.html
I had the same issue. Just solved it. Here is how:
Remove the base url.
Enter open or openWindow in command
Enter the file url in target e.g. file:///C:/temp/junk/SomeSiteAutomation/ABC.htm
Worked for me on FF 26 and Selenium 2.5
Open Selenium IDE - chrome extension
As soon as we open it will ask for project name and project url - just cancel it
Go to selenium IDE
In selenium IDE - in "command" text box select "open"
in "target" text box enter the path to sample html file as below
"file:///D:/index2.html"
Then this will show up in the command, target and value columns of the selenium ide.
Now just run the test. This will open up the local html file
I faced the same problem. I'm using Ubuntu and apache, but on Windows you can do the same.
move your index.html to /var/www/html (localhost points per default to this folder)
use http://127.0.0.1 as base_url in selenium ide
Right click on the Selenium IDE icon in the upper right of the browser window. Select "Manage Extensions" from the context menu. Toggle on "Allow access to file URLs" in the settings dialog.
This works in Chrome/Windows 10 and Version 3.17.0 of Selenium IDE.

Selenium: IE7 Not Launching

I am gettnig the exception:
"Failed to start new browser session: error while launching browser"
when trying to run a test suite with IE7.
Info:
python binding
using cygwin
I tried doing "*custom path_to_browser" and even printed out the path to browser directory in selenium module's do_command() function using os.listdir, and can see the iexplore.exe file. So I know the path is right.
I also tried setting localhost:4444 in IE7 and that didn't work either. Any ideas?
Use the new IWebDriver from Selenium v2 instead of Selenium RC. It will find your browser executables automatically (and now there's no need to start the Java Selenium RC instance anymore!)
This'll get you off the ground...
I'm using MINGW BASH on Windows XP SP3
(sorry, I can't get Markdown to render this as code, I've indented 4, then 8, phfhttt...)
#!/c/Python27/python
from selenium import webdriver
driver = webdriver.Ie()
driver.get("http://seleniumhq.org")
all_elements = driver.find_elements_by_xpath("//*") # pretty slow in IE
for index, element in enumerate(all_elements):
print "%03d element tag_name == %s" % (index, element.tag_name)
