How do I de-install Firefox 4 and return to the previous version?

Firefox 4 is incredibly slow. It is making it very difficult for me to work on the internet. I want to de-install it and return to the previous version, which was much faster. Please advise me about how to de-install Firefox 4. thank you, sj

Trash Firefox 4, and then install Firefox 3.6. You can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html

This is the first time that I have had a problem with a Firefox update. Does this mean that my computer is no longer secure to use Firefox? Do you think that I will be able to update to a version 4.+.+ when it is developed in the future?

Bonjour Tony, thanks for the input on restoring 3.6, but my understanding is that there are files that need to be saved from 4.0 to place back in 3.6 AND certain files that need to be deleted from 4.0 so they will not corrupt 3.6. I saw this on here and cannot find it again. I know it sounds confusing but I don't want to lose anything. So I want to be absolutely positive before I take this step into the unknown. Merci beaucoup!

@mjmcfarl3; Firefox is not only slow on windows7, I installed it in Ubuntu Linux and its terribly slow! Within 5 minutes surfing I closed Firefox and installed an other browser, WOW what a difference! I try FF two times again with the same result and for the first time in 5 years I quit FF.

Ya, unfortunately FF 4.0 on Ubuntu has been incredibly slow, and is locking up my system. I have in many years of running server and Desktop client versions of Linux, presently Ubuntu, never had lockups like this.

A bummer, because have been a faithful FF user. Can't now. Lock ups really surprise the bejeepers out of me.

Firefox 4 is not only slow on Windows 7 & Ubuntu but also on Windows Vista.

Long start up times, long waits for locations to open, RAM wrapped up to the max, navigation toolbar buttons randomly getting larger (larger than you can choose in options).

I can appreciate that many of the add-ons will need to be updated in the interim, but one,- FEBE, is sorely missed, certainly in the face of this problematic upgrade.

I also will be downgrading to 3.6 for now

Same problem in OS X 10.5. Firefox requires a full second or two to become responsive again between clicks. This includes link clicks, closing a tab, accessing menu, etc. Still, my first suspicion would be that one of my plugins could be the culprit. If after investigation I'm able to uncover anything, I will post back here.
