Strange. I have a tab hoarding problem, I often have over 1000 tabs open [1][2], and I cannot remember the last time Firefox crashed. I'm thinking it must have been years? I use ublock origin though, which might help since ads do their best to steal your computer and soul through any means possible of course.

I also use a bunch of other extensions though, dark reader, vimium, sideberry... I'd expect me to be a bit more exposed than the average user. Yet it's just rock stable for me. Maybe it just works better on linux?

1: I know this because I installed https://addons.mozilla.org/en-US/firefox/addon/tab-counter-p... to check :)

2: However after finding Karakeep I don't actually have 1000 tabs anymore!
