Certain websites (twitter, coinbase) crashes firefox and the entire computer, causing reboot.
For a bit over a week now, Firefox has been crashing and crashing the entire computer with it. I don't have issues with crashes or reboots in any other software and I've been using firefox for well over 15 years. I've tried disabling some plug-ins (Dark Reader, Simple Translate and DuckDuckGo Privacy Essentials), while still keeping uBlock as I consider it necessary (although any other ad/tracker-blocker will do). Really I use all these four plugins all the time. These sudden reboots don't happen with cpu load starting to go up or anything, it just turns off the computer and restarts it. It also only happens on certain websites like coinbase.com, twitter.com and I think it has happened on a swedish price comparison website, a once on a game sales listing website (G2A). It never happens right away, but after anything from 1 to 10 minutes of being on those sites.
It never crashes on youtube.com or bilibili.com, neither on nexusmods.com or mail.google.com or support.mozilla.org. I suspect it's limited to certain self-updating pages with lists or tickers in elements that update regularly, I first noticed it when i kept open a tab with the bitcoin course on coinbase.com over a week ago. I have recently gotten a newer very powerful graphics card, but I think this started before I installed it.
Any suggestions what to do about this?
