The crash reports are a little hard to interpret. Both crashes occur when Firefox is sending tasks to your ATI graphics adapter/chipset, but the circumstances are difficult to understand.

The first one seems related to WebGL, a layout technology, but when I try to inspect the code I get errors where the file cannot be loaded. Strange.

The second problem seems to occur when Firefox is rendering a video.

Could you start with the following:

Clean Reinstall

We use this name, but it's not about removing your settings, it's about making sure the program files are clean (no inconsistent, corrupted, or alien code files). As described below, this process does not disturb your existing settings. Do NOT uninstall Firefox, that's not needed.

(A) Download a fresh installer for Firefox 41.0.1 from to a convenient location. (Scroll down to your preferred language.)

(B) Exit out of Firefox (if applicable).

(C) Rename the current program folder, either:

(64-bit Windows folder names)

C:\Program Files (x86)\Mozilla Firefox


C:\Program Files (x86)\OldFirefox

(32-bit Windows folder names)

C:\Program Files\Mozilla Firefox


C:\Program Files\OldFirefox

(D) Run the installer you downloaded in (A). It should automatically connect to your existing settings.

Will Firefox start and run, at least briefly, or in Firefox's Safe Mode?

Note: Some plugins may exist only in that OldFirefox folder. If something essential is missing, look in these folders:

  • \OldFirefox\Plugins
  • \OldFirefox\browser\plugins
