Upon upgrading to version 4.0, my Norton Internet Security was disabled: 1. It no longer filters my internet interactions, 2. It no longer maintains its toolbar at the top of the screen, 3. It not longer remembers my passwords or user names, 4. It no longer fills-in my new contacts, with name, address, etc., 5. Its firewall no longer functions. 

  The directions for updating the firewall, currently in your "Support" section, does not, in any way, resemble the 2010 Version of Norton Internet Security screens, boxes, drop-downs, etc.

Symantec need to update their Firefox add-ons so that they are compatible with Firefox 4. They have indicated that for Norton 360 they plan to release an update to Norton 360 to support Firefox 4 in early May - http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20100720113635EN&ln=en_US

I do not know about the time scale for updates for other Norton products. Pending the update by Symantec, if you want to use the Norton add-ons you will need to downgrade to Firefox 3.6.

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.
