Now Firefox only crashes all of the time

more options

Firefox had slowed to a crawl...took advice on support page to delete and rename the "places.sqlite" file in the file manager under Firefox. Now Firefox only crashes all of the time. guess my decision to go back to explorer has been made for me...can't fix the newest versions of FIrefox hangs up, slow, error messages...now only crashes and the "places.sqlite..old" file I saved is now gone, so cannot even go back to it...

Firefox no longer works at all..?

Chosen solution

Sorry to hear about the crashes. If you are getting the Mozilla Crash Reporter form, your Firefox may have logged some data that would help track down the cause of the problem. You can submit that data to Mozilla and share it with forum volunteers to see whether it points to the solution. Please check the support article "Firefox crashes - asking for support" for steps to get those crash report IDs from the about:crashes page, and then post some of the recent ones here.

Note: If Firefox is not stable enough to use the about:crashes page, the article also describes how to check for submitted crash report IDs on disk.

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?

Thanks for the response, Well, in safe mode it will start and not crash.

When I go to the detail, it looks like APPLE icould extension may be part of the problem...I am also continuously getting Norton Antivirus scanning messages popping up for AppleBMDAVLoacalized.DLL which I believe is related to iCloud bookmark synchronization? https://crash-stats.mozilla.com/report/index/e975997d-bbc2-4b9e-98a5-f1c8a2151206

I removed the iCloud Extensions Synchronization in iCloud control panel (unchecked) , and removed from extensions in Firefox itself. Restarted Firefox and it started right up, and actually is MUCH faster has regained it's speed and loading of pages without errors.

Thanks for your assistance, much appreciated. Leave it to iCloud to cause issues...who would imagine? lol

Hi Doug, yes, try removing the "iCloud Bookmarks" extension in Firefox's Safe Mode. Two other Windows 10 users reported crashes related to that extension:

For anyone reading this who is not familiar with how to do that, open the Add-ons page using either:

  • Ctrl+Shift+a
  • "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Extensions. Then find iCloud Bookmarks on the right side and use its Remove button. Firefox will prompt you if you need to restart in order to complete the process.

Edit: You beat me to it. Congratulations!
