Why does my Firefox keep "not responding"?

[lazarus]

I may have too much open, 3 windows with about 45 tabs. Is that it?

I'm running Win7 on a Toshiba laptop with 4GB of RAM, so I don't think it's that. Just sometimes, it freezes for a while.

It's been this way through three patches of Firefox, at least.

1. The tabs might be it.

I'm assuming you are running the stable version of Firefox too, correct ?

You might want to run a malware scan with two programs to eliminate that cause too.

2. It's been doing the same thing to me, too

and I never have that much open. One window with maybe eight tabs tops, and I have 8GB of RAM now.

I was suspecting an old hard drive going bad until I read this. Now I think it may be a Firefox bug that only manifests under certain conditions.

Updating to the latest seems to have fixed it.... for now. That, however, may be because this is a fresh install of Win7, too.

3. Could be your profile's corrupt.

Create a new profile, see if that solves your problem.

Or it could be your plugins & extensions. Experiment with disabling them, see if that helps.

4. I'm having the same issue - with both Firefox and Chrome

When I close either, there is a process still running (either Chrome or Firefox, depending) that I can't kill from the task manager. Shutting down takes forever (trying to kill that same thing, I suppose, before shutdown) and it's the only way to get things going again.

I've disabled extensions, uninstalled and reinstalled... no difference.

All was fine until about a week ago.

5. Nosing around...

It may be connected to flash. (Would explain why I'm having problems with both Firefox and Chrome).

I've uninstalled that, and we'll see if that makes a difference).

But why would it suddenly start causing issues?

6. I've removed flash...

and I thought that did it. But not so much.

I did notice, in both Chrome and Firefox, that simply trying open a site like Target or Radio Shack would immediately freeze everything. Can't figure why that is.

7. One more hint

in case it's useful.
MWB on a deep scan found a few instances of Adware.WidgiToolbar.

Might this have been causing the problems?

8. back to freezing. This time when I opened DU

Frustrating!

9. So I mostly fixed it

I closed about 15 or 20 tabs. Still have three windows with 10 or so tabs each (and it's kinda necessary until I figure out this new tab manager thingy that just got introduced).

It's only frozen once or twice since I pared down the tabs, so I think that was it.
