Firefox 4 freezing all the time.

Can someone please help me? Firefox freezes on my computer all the time. As in every few seconds it will freeze, and I can't figure out what is causing this problem. I've had it on other browsers to a lesser degree. I've had this problem with Firefox since version 2.5. I'm getting a little sick of it.

Re: Firefox 4 freezing all the time.

Since this evening I have started having this problem too. If it continues I'll just go back to 3x or stop using ff altogether.

It's happening to me too, and it's affecting other programs I have running as well. I am not very happy with this.

Re: Firefox 4 freezing all the time.

I've been having the same issue. I'm actually using IE (ugh, I know, chrome wasn't installed on this specific computer) right now, and I'm having a better time using that than Chrome. This system, I was trying to search something in the URL and it froze on me. It's been frozen for an hour (I was searching to find if people had the same issue, and was too lazy to kill it)... and it makes me sad. I'm also having issues on my desktop system. When I open up PuTTy to get to a sql server and try switching between firefox and that, the thing hangs up. I *always* have to kill firefox after that. I have a dual-core 3.1ghz AMD Phenom II X2 550 Black, 8gig ddr3, a raid 1 config with two 1.5tb hds, and a 9800gt video card in that system... ohh and a 500w powersupply and Windows Ultimate 64bit

Re: Firefox 4 freezing all the time.

I had a similar problem when using Facebook in particular. I could not write a message due to the page freezing on me, very frustrating. Earlier on today I disabled the AVG Safe Search plug in (add on maybe) in the add on page. And since then I have not experienced any problems on Facebook or on the internet using Firefox 4. I had a similar thing happen when the new AVG 2011 was installed and disabled Link Scanner in the program itself because it was making pages slow and freeze. This problem for me at present began once AVG was enabled on Firefox 4. It wasn't compatible with the earlier version of Firefox but since two days ago it was awful. Hope this helps someone...........it worked for me!!

Re: Firefox 4 freezing all the time.

For me FF windows freeze in a way I cannot move the window around after switching tabs. Or the FF window moves sluggishly. No extensions/add-ons (only Skype but disabled). Sometimes can't move the window at all. I only have pages from msn.com and yahoo.com on the tabs. And various pages from FF support site. No other sites.

Almost unusable now.

Have to switch back to IE 9 now (which I don't want to!), until this window-freeze is resolved.

Re: Firefox 4 freezing all the time.

Just found out for me I turned off 'Use hardware acceleration when possible' and it seems the 'freeze on moving FF window' is gone.

https://support.mozilla.com/en-US/questions/800272?s=freeze+firefox+4+window&as=s

Still sluggish at times when moving a FF window. At least it's bearable.


I have 9500GT that supports DX10.


IE 9 is working fine w/ hw acceleration turned on watching YouTube HD videos -- pretty smooth, no sluggishness when moving windows.

Used this to test IE 9/FF 4: http://ie.microsoft.com/testdrive/Performance/FishBowl/Default.html

Result:

IE 9: 60fps.

FF 4 (hw acceleration OFF): 4fps


Going to use IE 9 for YouTube videos for now.

    • Someone needs to fix this FF4 feature (hw acceleration ON causing FF4 freeze on window--can't move around...).


This is for my case.

Re: Firefox 4 freezing all the time.

What happens with me is that Firefox ALWAYS stops working for a few seconds when I launch it, usually after two to three minutes of usage. It's not a big deal, just really annoying and it's made me switch back to Chrome. I'm running Windows Vista Business 32 bit with a 2.4 Ghz Core 2 Duo processor. It's not the computer honestly, because Chrome and Internet Explorer work perfectly.

Re: Firefox 4 freezing all the time.

I had reached the point where Firefox was freezing as soon as it launched. Recently, I had been getting the message the Firefox couldn't install the update completely. I realized finally that Firefox 4 was trying to update to Firefox 4.01. Using IE I downloaded Firefox 4.01 directly. After I installed it the freezing stopped.
