whenever I do a Firefox update, there sometimes is a new extension included that I personally feel no use or need for..most of the time I can disable them w/programs like Ccleaner (see image), but some are persistent, and return the next time I open Firefox. Firefox always consumed a significant portion of my 8gigs of RAM, and my latest update to 144.02, it is approaching 15%. Any way I can stop this short of reverting back to previous version?
