firefox 4 crashes constantly, on opening, different pages, etc. Old firefox worked fine

I updated to Firefox 4 on my vista laptop. I am running no redirect and a script blocker, both compatable with firefox 4. Firefox 4 keeps crashing, will keep loading the "well this is embarrassing" page, even when it starts normally, I will load a page, and within a few minutes, firefox will redirect to that page, then crash

Does this still happen if you restart Firefox in safe mode? For details, see Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

Re: firefox 4 crashes constantly, on opening, different pages, etc. Old firefox worked fine

For me it's still freezing/crashing in safe mode.

I downloaded Firefox 4.0 yesterday. It worked fine then, but it keeps freezing today, from the moment I open it and on.

I tried using it in SafeMode, and it was doing the same thing there. So this isn't an add-on problem.

This is very frustrating, and obviously a problem on Firefox's end, as Internet Explorer and everything else works perfectly fine for me.

This happens on Firefox for me no matter what site I'm visiting (AOL Mail, Google, just normal websites I visit, etc., etc.)

Firefox is unusable right now, and I have to use Internet Explorer.

There's obviously some sort of bug happening on Firefox 4.0 for some users, as I'm seeing a lot of users with this issue.

What can be done? Others have tried reinstalling, and that doesn't work. Plus, it's a pain as it took me hours to navigate and set up Firefox 4.0 the way I like it yesterday (including coding things the way I like...like having "open link in new tab" be underneath "open link in new window" like it was on the old Firefox). I do NOT want to do that again, especially since that remedy does not seem to be working for most.

Like I said, it worked fine yesterday, so this seems to be a recent issue. Any help would be greatly appreciated. Thanks!

By the way, I am using Windows Vista. Just trying to include all info that may be helpful.

If you have McAfee Site Advisor installed, you might need to download a new version to fix this problem: http://uk.mcafee.com/root/aboutUs.asp?id=sa&affid=0

I don't.

A few hours later it was working fine again. I don't know if it has anything to do with the fact that I redownloaded Firefox 4.0 (without me deleting the 4.0 version that was already on my computer), or if it has anything to do with the fact that my Windows explorer crashed and rebooted itself. I doubt it's the latter, as I'd rebooted my computer several times in an effort to get Firefox to work, and one would presume your Windows explorer automatically reboots when you do that.

I think it might just have randomly started working again, just like it randomly stopped working. I am hoping that this doesn't happen again. I know there are still many users who need help, and to me it seems quite obvious that there are still bugs and problems causing Firefox 4.0 not to work properly for some.

Anyway, thanks. I'll be back if it stops working again.

This is happening to me every single time I leave firefox unattended (minimized) for a a few hours. When I come back and open a new tab it just freezes out...

This is so frustrating and it never happened with old firefox.

I'm running on Windows 7.

PLEASE HELP!

I was thinking... just a wild guess: Could it possibly have something to do with Windows 7 login? My computer locks down with screen saver so every time I come back to use it I have to enter my password, then I try to use firefox and bam! it freezes...

Until I see a good solution posted here I'm gonna use chrome till a patch manifests itself...

BTW how did you switch the open link in a new tab / window order?

I installed firefox 4 a few days ago and it was working fine until today so the crashing has just started and for those of you who have not experienced it yet then I hope you don't but if they do not address the issue soon they are going to have a very big problem. I think until they resolve this issue I will go and use the dreaded IE 9 so I don't lose what I am doing right in the middle of it and have to redo it all. I am sure if they get enough complaints someone will get off their *** and take a look into the problem, but until a substantial amount of people complain about it they won't do a thing.
