I seem to recall a post from Dave Plowman about this a while back. I've used Firefox quite happily for years now but gradually it's been getting slower to load up and it's using huge amounts of memory. I've got a really old pentium pc with 512mb of ram and FF is going straight to 350mb of that just to start up. If I open more than one or two tabs it stops dead.
I tried it in safe mode with all the add-ons disabled and that did help but it's still not great. I suppose on a modern pc with gb of ram and a fast processor no one notices but it's screwing my ability to use the internet at all now. Given it used to be fine I have to presume it's the recent versions of FF that are the problem.
Thinking about reinstalling an earlier version or maybe just move to a different browser?
Suggestions?
