Ok Firefox 4 sucks. Plain and simple. When i used firefox 3.x.x I could have around 13 tabs open and nothing would go wrong at all. Now that i use firefox 4, i have to use less tabs or the browser would crash no matter what, and I have only 6 tabs open and i keep getting the (Not Responding) Sign and the browser freezes. How can I F#CKING fix this its bullsh!t. I have a $4000 gaming computer with 24gb of ddr3 ram and this is somehow sucking all of my ram too and making my harddrive constantly spin when firefox is open.

Firefox shouldn't be that slow, plain and simple. There's an extensive set of tests that go into making sure that updates to Firefox either improve performance, or are performance neutral, and these have been in place for quite some time.

I do however think the update is related to the slowness, just not in the way you might think. Older extensions don't always play well when upgrading Firefox - it's possible that there is an extension that's not working correctly. Take a look at Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems for some advice on how to tell if your issue is being caused by an extension.

Firefox hangs or is not responding - How to fix and Troubleshoot Firefox crashes (closing or quitting unexpectedly) are more general articles dealing with freezing and crashes - these may also help you.

You should also take a look at Troubleshoot Firefox issues caused by malware if you continue to have problems. Malware extensions and plugins can cause problems just like legitimate extensions and plugins - and are more likely to do so when upgrading because they tend to be poorly written.

If you've already tried everything else, then follow this Troubleshoot and diagnose Firefox problems guide. It's a fairly comprehensive set of steps that systematically eliminate all the likely causes for problems with Firefox. If that's followed it should get Firefox running as good as new.

If that still doesn't help, then you can find old versions archived at but keep in mind that you may miss important security updates by going back to an older version.

For a quick start you could give another browser a try to make sure you have a Firefox rather than a computer problem. A computer memory check could also be helpful - another user may be able to help on this.

You could also get rid of any third party toolbars.
