That's an interesting point. I shouldn't have to do that, and I didn't used to. And FF 105 is specifically supposed to be *better* for this, not worse! Sigh. OK, I'm remembering that slightly wrong. I thought 105 had CPU performance improvements, but it's really low memory improvements: https://www.mozilla.org/en-US/firefox/105.0/releasenotes/ * ... * Stability on Windows is significantly improved as Firefox handles low-memory situations much better. * ... * Firefox is less likely to run out of memory on Linux and performs more efficiently for the rest of the system when memory runs low. * ...

I'm late to this party, but I'll tell you what I've always done to partially de-pig Firefox, because Firefox is and has been for some time a slow, bloated, CPU wasting pig, and as time goes on it continuously gets worse. What I've done in the past is close all instances of Firefox, then move directories like ww3pxy54.default-default and qjdff5ox.default out of the ~/.mozilla/firefox folder, along with profiles.ini, because if you don't move profiles.ini along with the directories you'll get the dreaded "can't find profile" message and Firefox refuses to start. Beware that doing this removes your bookmarks, which I don't think should be associated with a browser anyway, all your cookies (I assume), and I'd imagine all your plugins. Don't delete the directories and profiles.ini, move them, just in case you find your new, faster Firefox lacks what you need.
I haven't tried, but it might be easier still to `mv ~/.mozilla/firefox ~/.mozilla/firefox.BAD`. I probably should try this, specifically because I have probably have old extension cruft, and general bloat in there. But I haven't, because then I lose...everything. I've got a large number of FF windows with a huge number of tabs open. I have a small number of extensions (OK, easy to work-around) and a bunch of bookmarks (esp. quick links; but also easy to export/import). And history, passwords (for sites I don't care about), and so on. I don't want to lose that stuff and start over. I guess at some point when I have an afternoon to kill I should try it, and then cherry pick what I still want to keep back into a new profile. So folks might pick on some of that and say, "Well you don't need a 'large number of FF windows with a huge number of tabs.'" Maybe not, but I *want* them, and it's my call. And up until FF 105, that worked fine. To add more confusion, FF 105 is behaving at $WORK now. From Tue to Thu my $WORK laptop fan was running much louder than usual, due to "firefox-bin" and "Isolated Web Co" each taking at least 50% of a CPU (and that VM only has 2 old CPUs). Thr at about 3:30 PM that stopped. No clue why, I did nothing I'm aware of, and since then it's been fine. Meanwhile my home PC has 754.5% CPU for "WebKitWebProces", but "firefox-bin" and "Isolated Web Co" are fine. WTH?
