When I click on a link in an email or on a web site, I have to highlight the URL and then press enter for it to load. I also lost both my password plugin/toolbar (Billeo and Norton) and now can't get in a lot of my web sites as I did not memorize the passwords. I don't remember a script telling me which plugins would not work with version 4. Turns out I very happy with version 3 and just didn't know it. Please let me go back. Thank you, Don Carter

Just had to do the highlight and enter on the about:support in the address bar.

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.
