Hmm, so I left that link above running in an active Firefox tab for about an hour and a half and didn’t see any crashes. I’m wondering again if you may have an obscure hardware issue. Either that or perhaps Fedora recently pushed out an update that fixed that issue. In any case I hope this might help to know. Have a good day!
Pop OS is excellent. You wouldn’t really know it’s created by a corporation. It’s basically just the build they run on their hardware but I’ve not seen anything in it like ads or anything limiting my freedom. My perception of it is that it’s just a more friendly and (snap-free) Ubuntu and I concur with those saying Nvidia is smoother on it. It does have a modified gnome but coming in the near future is their own DE called cosmic which seems promising. If it ends up being bad I will probably just switch to fedora even though Debian based distros are more supported. Been loving fedora on my new laptop
