I want to back out of FF 4.0 and go to older version 3.6 because I cannot use Norton 360 that I absolutely need and rely on. Can someone send a link about how to uninstall 4.0 and reinstall 3.6?

Symantec are working on updates to make their add-ons work with Firefox 4. pending this, to revert 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.

Thank you for the feedback. Your advice worked. I successfully uninstalled FF4.0 and reinstalled 3.6. Everything functions as before.
