Example: Clicked on a link in a emai from THIS GROUP trying to answer this problem. The responses did not fit so I hit the back button and again got the Fastmail.has stopped working screen.

Has also happened when accessing a site directly through Firefox and the backing up

I am running Firefox 151.0.4 on a Win 11 (25H2) AMD Ryzen 5, 32 GB ram. Every time I close Firefox, it generates a crash report. That takes several minutes during which I can't start a new Firefox window. The crash report says the report was submitted successfully but when I look in about:crashes the reports shows they need to be submitted.

I ran in troubleshoot mode and disabled all plugins and did not see any extensions listed. I restarted and it still crashes. Firefox seems to run fine. But the crashes when it closes are annoying and disruptive.

here are the first few lines of a recent crash report: Firefox 147.0.1 Crash Report [@ shutdownhang | mozilla::SpinEventLoopUntil | nsThreadPool::ShutdownWithTimeout ]

I had this trouble after Firefox's previous update, where the browser would just close as I was in a tab. It had stopped so I thought the problem was fixed. However, it just updated the browser a few days ago and again I'm having a problem where the browser will just close in the middle of me entering information. It does not have to do with which program I am in as it just seems to happen randomly. It does not save any information I've typed in.

Thunderbird is very glitchy and slow after the latest update - Thunderbird 140.11.1esr (20260522210329)

Especially, when I get a new email, Thunderbird stops responding for 5-10 seconds and then starts working.

I am using Windows 11
