I ended up opening up firefox again when CCleaner asked to update. I updated and ran that. Updated avast... rebooted...
Then, back to firefox. Suddenly there's lots of lag. flash crashed. Scrolling through a facebook group caused firefox to freeze multiple times. Thought it was facebook... tried scrolling through google images(first thing I thought of where I'd be able to scroll for a bit) and it didn't show the "not responding" message I was getting while in facebook but it was indeed freezing up a bit and in fact crashed at one point.
Java needed an update... so, I did that. No change. Flash is up to date though I forgot I'm actually running the newest... previously I'd been having a LOT of trouble with facebook games with the newer versions of flash, where flash has its OWN plugin container(s).
Anyway... other than avast updating(which it said updated to make the firefox plugin more STABLE) I don't think I've done anything else prior to the buggyness that could cause firefox to be that way.
when it starts lagging and I go into task manager... it's using up more than 40% of the memory(I have 4gb) with only a couple of firefox tabs open and thunderbird... saw firefox eating up 600+mb of ram a few times while I wasn't really doing anything. CPU usage was bouncing up and down largely from firefox... up to 75% at one point.
I'm certain something is off with firefox... question is, what is it?
I guess I can try disabling the avast plugin and see how it reacts then... and I can reinstall firefox.
Just really odd how the behavior changed so fast. I'll try a few things but figured it wouldn't hurt to post the problem for now. Will update if anything changes.
Edit: Well, it was avast's webrep addon. I disabled it and restarted firefox... went to the facebook groups and to google images and I was able to scroll smoothly without it freezing up at all. Hmmmm... This avast update was supposed to IMPROVE its addon... Grrr... I can live without it. I use web of trust as well and am fairly careful where I go anyway... maybe avast's next update will be better?
