Tabs crashing

Tommo

About two weeks ago multipel tabs started crashing nin Firefox 105. If I close then re-open Firefox everything worked fine for a minute or two, then the tabs crashed again. Clicking on the restore tab button had no effect. A few days later, this stopped happening and everything seemed OK, then there was another Firefox upgrade and the whole thing started again. I've had Firefox for about fifteen years and don't want to move to another browser, but I can't keep switching it on and off like this, it's annoying and a waste of time. I've had to start using Edge, where this problem doesn't exist. I've tried various solutions but nothing seems to work. The only thing that may explain it is that I've noticed in Task manager that the Ethernet throughput is far too high - the leaks go through the top limit. Can anybody help? I'd be very grateful to be able to use Firefox again.

Could you test in Firefox's Troubleshoot Mode? In that mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is running:

You can restart Firefox in Troubleshoot Mode using either:

  • "3-bar" menu button > Help > Troubleshoot Mode... (before Fx88: Restart with Add-ons Disabled)
  • (menu bar) Help menu > Troubleshoot Mode... (before Fx88: Restart with Add-ons Disabled)

and OK the restart. A small dialog should appear. Click the Open button (before Fx88: "Start in Safe Mode" button).

If Firefox is not running:

Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.) A small dialog should appear. Click the Open button (before Fx88: "Start in Safe Mode" button).

Note: Don't use the Refresh without first reviewing this article to understand what will be deleted: Refresh Firefox - reset add-ons and settings.

Any improvement?
