How can I go back to the version before Firefox 4?
I use a program called RoboForm2Go which stores user names and passwords. I have installed them on a flash drive. I can't use that program with the new FF4, doesn't give me a toolbar for that program. It worked fine when I had the previous version of Firefox and would like to go back to that version.

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.

TonyE, Thanks for your help with this. I uninstalled FF4 and installed FF3.6 and can get the RoboForm2Go to work but it works differently than before but at least I can use it. Thanks!!!
