Sorry to hear about the crashes, and thank you for submitting reports. In order for support volunteers to see your reports, we will need some information from you. Please check the support article "Firefox crashes - asking for support" for steps to get the crash report IDs from the about:crashes page or from disk, and then post some of the recent ones here.

Also and/or meanwhile, could you test in Firefox's Safe Mode? That temporarily deactivates extensions, hardware acceleration, and some other advanced features of Firefox that might make it more prone to crashing on some systems.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

  • "3-bar" menu button > "?" button > Restart with Add-ons Disabled
  • Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any less crashy?

Your Firefox identified itself as the "Beta" version, Firefox 48, which is still in testing. Would you be interested in switching back to the "Release" version, Firefox 47? If so, here's how I suggest doing that:

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 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 47.0 from https://www.mozilla.org/firefox/all/ to a convenient location. (Scroll down to your preferred language.) For maximum plugin compatibility, choose the regular Windows version (32-bit) rather than the 64-bit version.

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

(C) Using Windows Explorer/My Computer, rename the program folder as follows:

C:\Program Files (x86)\Mozilla Firefox

to

C:\Program Files (x86)\OldFirefox

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

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

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

Hopefully the new install will be more stable. Any improvement?
