Now in version 84,0 (64-bit) version tabs crash very often. Never before.

Just now I had been browsing on several tabs and watching Netflix on another screen. I checked in Task Manager (screenshot attached). Which showed 83% memory usage - but by arranging all running programmes this could not be correct as I have 32Gb RAM. Speccy report attached. I closed Firefox. No change in either Task Manager or Speccy on memory usage. Then I ran System Mechanic Pro which cleared a lot of junk internet files. And then checked Task Manager and Speccy again: 9% memory usage. This sounds about right.

My amateur assumption is that this version of Firefox does not clear closed tabs etc from the RAM memory - which leads to it becoming clogged.

Pros should know. And be able to solve this nuisance.

Thanks for help!

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

We have recently seen multiple reports that Bitdefender is causing issues with tab crashes in Firefox 73.

It looks that Bitdefender has pushed an update to address this issue 21 Feb 2020
