How do I roll back version 4 to the old 3.6 New version 4 is impossibly slow

ststelly

I have disabled all add-ons to try and speed up version 4. It did not work. I would like to go back to 3.6 How do I accomplish that? I have slow dial up to begin with, and if I open more than one tab, nothing else will load. I am sick of time-outs with your new and improved vs. 4

To downgrade to Firefox 3.6 first uninstall Firefox 4, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data.

You can then install the latest version of Firefox 3.6 available from http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your current bookmarks, passwords etc.

To avoid possible problems with downgrading, I recommend going to your profile folder and deleting the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Deleting these files will force Firefox to rebuild the list of installed extensions, checking their compatibility, and reset toolbar customizations.

Thanks Tony, worked great
