Firefox does not work after update to 3.6.6 (and all later revisions)

(EDIT: I found the exact revision from which the Firefox is not starting, it is 3.6.6 so I changed them throughout this post, previous revision value was 3.6.8)

I am using Windows 7 x64

After Firefox recently updated to 3.6.6 it does not work any more. The application is listed in task manager but it does not do anything. There is no user interface or anything. Only way to interact with it is "End process". Starting in safe mode or starting Profile manager is not possible.

I tried all possible and suggested solutions in mozilla KB, this and other forums but without success (windows safe mode, firefox safe mode, renaming firefox, waiting, checking for firewall or malware/virus issues, deleting profile, uninstall, clean reinstall and every possible combination of those that I could think of). Always the same result, no error message, firefox shown in task manager and that's it. When I do clean install of all later firefox revisions starting from 3.6.6 the problem remains, including latest Firefox 4 beta6. I have no issues with any firefox versions on my Vista laptop, so I would guess that something in my windows environment is not suitable for newer versions of firefox.

As I cannot find official older 3.6.x revision of Firefox, I am currently using 3.5.13 and it works flawlessly.

Any help is appreciated, I ran out of ideas.

You can try a direct connection and select No Proxy in the connection settings.

You can find the connection settings in "Tools > Options > Advanced : Network : Connection"


Also do a malware check with a few malware scan programs.
You need to use all programs because each detects different malware.
Make sure that you update each program to get the latest version of the database before doing a scan.

Hi guys, time to report back some news. Today I tried to run firefox again (as beta 7 was out) and some magic happened. I was presented with an update message window and compatibility report on some add-ons. Firefox started. :)

I did nothing, I installed nothing, uninstalled nothing, done nothing whatsoever that would cause this to happen. So my conclusion is that whatever was causing problems in previous releases is now no longer present in Firefox 4 beta 7. My problem is solved.

Thanks all of you that tried to help, and dev's that have done the great job.
