Firefox 36 breaks WebDriver 2.44.0

[lukeis]

Originally reported on Google Code with ID 8399

Firefox 36, Windows 7-64, current updates.

Steps to repro:

Using latest python wrapper:
https://pypi.python.org/pypi/selenium

and running basic code:

------------
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://seleniumhq.org/')
------------

... launches Firefox, but then hangs in FirefoxBinary.launch_browser() at self.wait_until_connectable.

Output from Firefox console:

For what it's worth, if I (un)revert https://code.google.com/p/selenium/source/detail?r=d18b9fd36afab5680d5a735d2fc73eb484be0d05,
Firefox 36.0b6 works just fine. (Apart from the performance regression that led to
that revert in the first place.)

Any updates? Firefox 36 stable will be released in about a week...

While classified as a medium priority issue, it seems to be a major issue for QA / automation
team across the world.
It seems like this will block automation for anyone wishing to run on FF36.
Functionally-wise this is very low priority (browser user not impacted); However on
the testability front, this is a major issue (no automated tests can be ran).

(So it seem like the FF team is not using Selenium internally for testing some of their
changes; they would have hit this otherwise)

Is there any idea when this will be resolved - we're relying on it for our WebDriver
automated tests on Firefox.

Need this resolved as well as soon as possible.

I'm having the same issue, and this is critically important.
