I was also facing the same problem and I spent more than a week to fix it. Restarting my machine seemed to have fixed it, but only temporarily.

There was a solution to increase the maximum number of ephemeral ports by editing the registry file. That seemed to have fixed the problem but that also, only temporarily.

For sometime, I kept thinking if I was trying to access a driver which is no longer available, so I have tried to call:

driver.quit()

And then recreate the browser instance, which only gave me: SessionNotFoundException.

I now realized that I had used BOTH System.setProperty as well as ffCapability.setCapability to set the path of the binary.

I then tried with only System.setProperty => No luck there.

Only ffCapability.setCapability => Voila!!! So far it has been working fine. Hopefully it will work great when I try to re-run my scripts tomorrow and the day after and the day after... :)

Bottomline: Use only this

ffCapability.setCapability("binary", "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe"); //for windows`

Hope it helps!

It seems that Firefox gets installed in the App data folder Path C  Users users AppData Local Mozilla Firefox  So you can set the firefox bin property as below  System setProperty  webdriver firefox bin    C   Users   USERNAME   AppData  Local  Mozilla Firefox  Firefox exe      Adding this resolved the issue for me

For me it was just a matter of changing the path variable to   C  Program Files Mozilla Firefox  instead of  C  Program Files  x86  Mozilla Firefox

User · Answer

For some reason  adding the environment variable didn t work for me   I was able to specify a path to Firefox in the command line node configuration  as described on this page  grid2    -browser    browserName firefox version 3 6 firefox binary c  Program Files Mozilla Firefox firefox exe  maxInstances 3  platform WINDOWS

I was also suffering from the same issue  Finally I resolved it by setting binary value in capabilites as shown below  At run time it uses this value so it is must to set   DesiredCapabilities capability   DesiredCapabilities firefox    capability setCapability  platform   Platform ANY   capability setCapability  binary     ms dist fsf PROJ firefox 16 0 0 bin firefox      for linux    capability setCapability  binary    C   Program Files  Mozilla  Firefox  msfirefox exe      for windows                 WebDriver    currentDriver   new RemoteWebDriver new URL  http   localhost 4444 wd hub    capability     And you are done    Happy coding

Open Command line  Start -  Run -  type  cmd   type PATH  Verify that you can see here written C  Program Files Mozilla Firefox15 Firefox exe   It will be probably not here - because thats what the error says  How to fix it    Click Start Right click on  Computer  and click  Properties  In left menu Choose  Advanced system settings  Go to tab  Advanced  and click  Environment Variables     In the window below select  Path  and click  Edit      Admin rights needed  Add at the end the desired path  semicolon separated Possible restart of computer needed   It his does not help then change the constructor like this   File pathToBinary   new File  C   Program Files  Mozilla Firefox15  Firefox exe    FirefoxBinary ffBinary   new FirefoxBinary pathToBinary   FirefoxProfile firefoxProfile   new FirefoxProfile    FirefoxDriver  driver   new FirefoxDriver ffBinary firefoxProfile

you have to add vm argument while running the program  This should be like   -Dwebdriver firefox bin  custom path of firefox exe   In IntelliJ IDE much simpler Goto Run   Edit Configurations    In VM options add the above     Eclipse also have the options to give vm argument while running  This way I am using portable Firefox with selenium
