No clue to be honest, I just opened it on a single tab of Reddit and it was using high single to double digits of CPU sitting there. I looked at the bug again with fresh eyes and it seems like there is a deeper issue that may be my fault. I am running i3-wm and it seems like Firefox gets stuck in a loop if you don't have all the fonts it expects. I had a previous issue where I was crashing my terminal when a program tried to show emojis, which was a legitimately a fun issue to figure out. https://bugzilla.mozilla.org/show_bug.cgi?id=1495900 https://bugzilla.mozilla.org/show_bug.cgi?id=1495900 https://bugzilla.mozilla.org/show_bug.cgi?id=1499385 https://bugzilla.mozilla.org/show_bug.cgi?id=1499385 (not sure if this was the one I saw before giving up + installing Brave, but the fact there are _tons_ of "Firefox hitting 100% cpu" is telling)
