When I open one tab on Firefox, my task manager shows multiple programs running along side it. I know some extra processes are needed but this seems like an unusual amount. I have included a screenshot of the tasks that appear. When I try to delete these, they reappear. I have tried various online solutions such as uninstalling and reinstalling, and checking various settings. It is affecting my computer's performance and I am not sure how to solve this. Thank you!

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.
I need to 'clear the cache', apparently. How do I do this, please?

I am a heavy Firefox user, and have been using it (and its predecessor) since Netscape. In the last year, the size of my Firefox profile has more than doubled, from 500MB to 1.3GB. What's the probable cause(s), and what can I do about it?
