I have this problem, mine freezes for about 2 minutes regularily. I have done a clean install and I still have this issue. Did a virus scan as well as as spyware scan also. Nothing. This does seem to be more of an issue the more tabs I have open. I can't remember getting this with just one tab open. More tabs, the more it freezes and/or crashes it seems.

I'm sitting here nodding my head... I've run virus and spyware scans too, as well as reinstalled Foxfire three times to no avail. I don't have any add-ons except for AdBlock running. However, Foxfire freezes even with one tab open. I don't understand it. Foxfire, up until now, has been the best browser I've ever used. Now I'm not so sure.

My laptop also froze frequently. Now it seems to work. It seems that the fingerprint reader add-on caused all this trouble (Digital Persona). I never installed this add-on, it was probably installed automatically with the fingerprint reader. Although it was shown deactivated, it caused all these troubles since I updated from firefox 3.x to 4/5. Even after fresh install of firefox this add-on was shown again (as deactivated) in firefox. There was no deinstallation button to remove it. I had to delete the add-on subdirectory in digital persona program folder. Maybe you have same problem as me.

Firefox Hangs

Check and tell if its working.

I tried what was listed in the link you gave mha007 and none of it applied to my browser, what few did had no effect on stopping the freezing.

I have this problem too and it seems it's for almost everything. From loading a different website, changing, tabs to opening my history. Firefox is the only browser I have problems with, and I know other people who are having problems as well. It seems since Firefox 4 came around there's been nothing but problems with it

i have this problem to. it seems to be connected to if i click something to download or go to another page it freezes for about 2 min. if u click on the page it says firefox is not responding .

@jimole2000 see the link in my First post + the following link:

Firefox is already running but is not responding

https://support.mozilla.com/en-US/kb/Firefox%20is%20already%20running%20but%20is%20not%20responding

Check and tell if its working.

i was having a HUGE problem with firefox 5.0 freezing up on windows 7. if i tried to download something with the firefox video downloader add-on, it would freeze until it had finished the download, sometimes 3 or 4 min later. what i did was, uninstalled firefox 5.0 and reinstalled 4.0.1. i think 5.0 may have been conflicting with my anti-virus (McAfee) it got a little better, but i was still having some freezing issues. then i found (on top left of browser in the Firefox tab) the PRIVATE BROWSING option. in private browsing, the computer doesn't save the history of your internet session. there are no cookies, history of sites and passwords (it can suck having to sign in every time) saved by the computer. after the first time i tried the private browsing option, my computer freezes are VERY rare.

it probably won't help everyone, i've tried so many suggestions from this page posted by others that didn't help at all for my problem, that i thought when i found something that did work for me, i should share it.

I have been having this problem. I thought it was my computer and was ready to reload Windows 7. But I noticed I didn't have the problem of the web browser freezing with IE or Google Chrome. Chrome smokes! I'm sticking with it until I hear FF is fixed. . .

I HAVE THE SAME PROBLEM AND I HAVE THE MOST RECENT FIREFOX AND I AM ABOUT READY TO GET RID OF FIREFOX AND NEVER USE IT. I HAVE NO IDEA HOW TO FIX THIS AND I DO A LOT OF WORK ONLINE SO IF I DO NOT HAVE A RELIABLE SOURCE IT IS TIME FOR A CHANGE.

@jlesko - Will you tell what are the problems you are facing ??

This issue is why I installed and am using chrome as my default browser :(

-> Firefox hangs or is not responding - How to fix

I came here after Firefox all but died on me: waiting a minute or more to open a simple page, and unfortunately none of the above suggestions did anything. I completely wiped out a previous installation, only to find out that the fresh new installation suffered even more freezes.

I finally did a mallware scan, and discovered that msseedir.dll is the culprit in this case.

Please do a search on your machine (I used Malwarebytes anti-malware), and maybe you will find the same dll responsible for the freezes.

You could try decreasing the max connections setting and see if that helps.

You could also try disabling hardware acceleration. Preferences/Options > Advanced > General > uncheck "Use hardware acceleration when available".
