For some weeks I have ad an issue with Firefox using 50%-100% of CPU. Normally it is the Firefox process itself, sometimes it is also "Privileged Cont".
OS is Kubuntu 24.04. Firefox has done this across 2-3 versions.
Things I have tried:
Restarting Firefox No change, I'll even get 100% cpu usage with no tabs open
Refresh Firefox to remove settings and addons No change
Uninstall Snap and try direct Apt package No change
Remove ~/.mozilla to fully remove any residual settings/cache/etc No change
Try with and without hardware acceleration See: https://support.mozilla.org/en-US/questions/1308215 No change!
I would blame my old computer hardware, but Brave runs fine. I am now using Brave, but would dearly like to return to Firefox as I miss containers, and I don't support a chromium dominated web.
