After a major windows 10 update, Thunderbird and Firefox crash continuously, usually the moment I open another program, rarely when using Thunderbird and Firefox. Reinstalled Firefox, but it still crases. These two are the only to have problems after update. Do you have a solution? Thank you and good day, Luciano

Thank you, I started Firefox in Safe Mode and it didn't crash anymore

It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.
