This new version IS TERRIBLE!! >>> HATE IT!! Want older version restored immediately or I'm going to a new browser!! This SUCKS!!
My favorite / most visited sites are no longer highlighted, cursor no longer works at bottom of my Email page to scroll, my 'go back a page no longer eact and on & on. Trying to tell every one I know to NOT DOWNLOAD firefox 4. Want my old version back, but don't know how to do it! Going to change browsers if this can't be restored to my satisfaction

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.
For details of how to find your profile folder see https://support.mozilla.com/kb/Profiles
If you do not like the new UI, you can make Firefox 4 look and behave more like Firefox 3.6, for details see http://www.computertechtips.net/64/make-firefox-4-look-like-ff-3-6
