C # Selenium WebDriver - FirefoxDriver error: failed to start socket at 45000

Question

I get the following exception when I try to run selenium C # webdriver scripts using Firefox browser.

OpenQA.Selenium.WebDriverException was unhandled by user code HResult=-2146233088 Message=Failed to start up socket within 45000 Source=WebDriver StackTrace: at OpenQA.Selenium.Firefox.Internal.ExtensionConnection.ConnectToBrowser(Int64 timeToWaitInMilliSeconds) in 

The same scripts worked fine two days ago and are not sure why they are not working right now.

• I added selenium DLL directly to my PROJECT and without NUGETS [I don’t know what it is]
• I tried looking at netstat and could not see that any port is working on 45000 cmd> netstat -abno | find / n / i "45000"
• I tried to remove the entire automation package and checked the code from SVN. DIDNT WORK
• I delete the firefox profile, uninstall and install the new firefox profile. Did not help.

This is pretty surprising, as it causes this error all of a sudden, and within a few months I run these scripts and work perfectly. The same “Solution” works on different PCs, as well as firefox, and works in the Chrome browser on my machine.

PS - I use selenium 2.23 and I don’t think I need to update the version, as well as the same scripts that work fine on another machine.

Could you tell me any alternatives, I can try to fix this, please.

Answer 1

I had the same problem and decided to upgrade it with Selenium packages with NuGet .

I would recommend you add NuGet to Visual Studio and add Selenium packages this way, and this will probably solve the problem for you.

I also had problems with Chrome and IE drivers for Selenium , which are not available through NuGet , and I solved the problems here by downloading the latest versions from Selenium .

Answer 2

You need to use the appropriate version of Firefox with a selenium IDE.

You probably need to downgrade Firefox or update the Selenium IDE, like Arran's comment.

I had the same problem because I had selenium 1.9 and Firefox 17, but this version of ide should be released:

Selenium Release Notes

1.10.0 (to be released) New - Added support for Firefox 16 and 17

1.9.1 New - Added support for Firefox 15

1.9.0 New - Added support for Firefox 14

Answer 3

The problem can be solved if all components of selenium (RC, Support, WebDriver, WebDriverBackedSelenium) are removed through NuGet and installed again through NuGet.

Answer 4

I had the same problem and solved it by upgrading my version of Selenium to 2.31 and then reinstalling firefox because it was localized in Program Files (x86) / Firefox 3.6 / (I always updated it to and its location has not changed from version 3.6). After reinstalling and rebooting, everything works fine.

Answer 5

My problem was resolved with

• copying the test project to several levels directly
• into a new solution
• is no longer in the directory.

I knew that something happened when the same code and the same project that worked in one folder did not work in another.

Remove the dll dll webdriver added to your project and install the new DLLs from Nuget. I got the same error, I added Firebug to firefox, or maybe it was updated, so older versions of the DLL did not support.
