Before beginning your downgrade, we would like to warn you that the extensions you have installed in FF3 will no longer work in Firefox 2, in most cases. But go ahead, see which all are not working and be ready to reinstall the ones that are not compatible.OK, let's start. Here is what you should do:
- Create a back up of your profile directory
See this link to find where your profile directory is. Then create a copy of this directory in some convenient location. Read the link for more information. - Download Firefox 2
This can be a bit daunting. That's because the Firefox site no longer gives you a link to download Firefox 2. The site talks about nothing but Firefox 3.
Or is it? Get Firefox 2 from http://releases.mozilla.org/pub/mozilla.org/firefox/releases/2.0.0.14/win32/en-US/. Linux users, you are smart enough to guess where Linux version would be, right? - Uninstall Firefox 3
You can uninstall FF3 using the Control Panel -> Add/Remove programs or by running the [Firefox Installation Directory]\uninstall\helper.exe
Select not to remove your profile information.
Linux/Ubuntu users you need to runsudo apt-get purge firefox-3.0 - Install Firefox 2
Though most of your addons will be rendered un-usable, you can still have your bookmarks and passwords list saved. Ensure that the old bookmarks.html and key3.db files are still in the profile directory. Rename signons3.txt to signons2.txt.
Now, install Firefox 2, and if all went correct you will have your bookmarks and saved passwords intact in your Firefox 2. Now it's time to reinstall all addons that Firefox have marked as not-compatible.
Ubuntu users need to runsudo apt-get install firefox-2to install Firefox 2. For other distributions, download the tar file from the above said Mozilla Releases site and untar it to a suitable location.








oh thank you, thank you, thank you
I can't thank you enough.
This is just what I was searching for.
This post on how to get my Firefox back to 2 was a lifesaver !!!!
The Firefox 3 was awful from the minute I installed it. My computer crashed about ever 15 minutes and when it was working, I could only use 1 tab at a time or it would lock up.
I love Firefox but until they get the bugs fixed, I am staying with 2.

Alternative:
Install firefox2 and/or 3 as a "portable application". The portable versions retain all settings in the application directory. Using this method you can switch back and forth between two and three whenever you feel like it.

umm it wont let me download it.. its been blocked. by fire fox 3....
I haven't tried it yet but I'm glad to see I wasn't the only oen who despised the monstrosity that is version 3...
Not only is it hard to use and filled with one 1-5 'useful' improvments out of the 15000 they promised...
But it also seems demonically possessed.
Regardless of what I type in the url bar the damned thing pops up options (which I specifically told it not to do) and they all lead to something about my ex. DX
The thing is a freak of reality and should be burned in the depth of internet oblivion.
Thanks!
