Firefox 99 hard crashes my computer

This is not the anser to previous post’s questions.
I do run FF99 both on a 12 years old i3 + radeon and on a brand new rysen 5600 with RX5500
4 to 5 simultaneous instances, each with 20 to 40 tabs.
No crash, ever.
FF much faster than Chromium or any fork like Vivaldi, Opera or else.

But, the computers are dust free, and the add-ons under control.

What is the outcome of proposed command ?

As answered earlier in this thread, there was only one add-on, and disabling it and also running in safe-mode made no difference.

Maybe completely unrelated, but I’ve been having consistent tab crashes in Firefox since the last update. Definitely something that’s changed in the system as it happens with previously installed FF (with brand new profile, safe mode, etc) & downloaded binary, but not flatpak version.

I am writing down all of the things related to Mozilla Firefox 95.0.2 was released on December 19, 2021; it fixes a single crash issue that affects certain AMD processors on Windows 7, 8 and 8.1 devices.

The new version of the Firefox web browser comes just a few days after the release of [Firefox 95.0.1], and about two weeks after the release of the last major version release of 2021, [Firefox 95.0].

Firefox 95.0.2 is already available. Installations should receive the update of the browser automatically, provided that automatic updates have not been turned off. Affected users, those on AMD devices on which Firefox crashed frequently recently, may want to run the update as soon as possible to address the issue.

Select Firefox Menu > Help > About Firefox to display the installed version and run a check for updates. The new version should be picked up and installed automatically at this point.

The official Firefox 95.0.2 release notes list a single fix:

Addresses frequent crashes experienced by users with certain AMD CPUs running on Windows 7, 8, and 8.1

The issue appears to affect Firefox running on Windows 7, 8 and 8.1 systems only. Only systems with AMD CPUs are affected, but the release notes don’t provide more details on the matter.

Firefox ESR, the Extended Support Release version of the browser, is not affected by the issue. The last version, Firefox ESR 91.4.1, is not changed, therefore. It was released just a few days ago alongside Firefox 95.0.1 to address a connection issue that affected several Microsoft domains and two crashes in the Linux and Windows versions of the web browser respectively.

Firefox 95.0 was released on December 7, 2021. It marked the availability of Firefox in the Microsoft Store and introduced a number of improvements and fixes besides that.

Interested Firefox users can check out the official release notes on the [Mozilla website].

It is also important to run a full system check for your PC using powerful antivirus software. There are a lot of third-party antivirus programs you can use but you can also use Windows 10 Defender to scan your system.
