The same thing happens with Selenium Version: 2.53.0

When watching the behavior live, then one can see that Firefox hangs right after it is opened by Selenium (the Fx GUI can be seen).

You will need to use the new Firefox driver from version 47 onwards. See https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver for details.

The add-ons signing feature of Firefox has now been pushed to version 48, so when 47 is released it should still be supported. I'm going to unlock this issue to allow users to report if they are still seeing problems after Firefox 47 is released.

Firefox 47 has not been released yet (it should be out later today). Please refrain from commenting unless you are using the official release of Firefox 47, preferably with the latest version of Selenium (2.53).

I'm using the Fx 47 build that will most likely be declared today as the official one (from here: https://ftp.mozilla.org/pub/firefox/releases/47.0/ ) - and still experiencing the issue here, so it seems the addon signing hasn't been pushed to 48...

This issue has nothing to do with addon signing. Something in FirefoxDriver is causing Firefox to have a startup crash.

We appear to be ticking something in the JSRuntime https://gist.github.com/AutomatedTester/8c011e194e6343b6d9bfbda80af76402

The issue is that code to support cert override was changed in a way that broke Selenium which in turn then crashed Firefox. There is a fix in the works from Mozilla.

As a work around you can either revert to Firefox 46 or you can use Marionette*. We have documented how to get set up with Marionette on MDN.

• Note : When Extension Signing ships in Firefox 48 or later the current Selenium WebDriver addon approach will no longer work and you will need to update to Marionette.

[AutomatedTester]

Looks like this patch, once verified, may only be out next week. I strongly suggest people move over to Marionette or downgrade to Firefox 46/ESR 45.

[AutomatedTester]

This has been fixed in Firefox, will close this bug when it is released

[AutomatedTester]

Firefox 47.0.1 has been released with a fix. We now need to release client libraries to pick up a version bump in the xpi that is used by FirefoxDriver

[AutomatedTester]

Most, if not all, of the clients have been released by now

it's also now in maven central
