Issue with Firefox and Add-ons

I'm more then sure this issue has been answered a 100+ times so here goes

I updated ff3 over the top of ff2.x and tried to update the add-ons/themes. Noticed that once I closed the browser, all the updates (both add-ons and themes) were basically rolled back to before they were updated. Without being updated, nun of the add-ons and/or themes worked with ff3.

Also tried downloading a fresh copy of ff3 portable, without any luck. Tried installing the FoxyTunes 3.0.2 add-on and once the browser was closed, the add-on vanished.

Also tried changing the Cache to 1000, but didn't change anything. This doesn't happen with the install version of ff3. All the add-ons/themes worked great with the 2.x line for me.

Should I copy the add-ons from my local machine to ff3 portable?

Thank you for your time
