Always get '1 new add-on has been installed' when launching FF

Hi, I think an incompletely installed add-on may be causing the 'Add-ons' window to always be displayed when FF launches.

- FEBE extensions backup warns about one it can't process, and hangs. 'Could not process extension/theme with GUID {DDC359D1-844A-42a7-9AA1-88A850A938A8}(133) -- skipped' (Note this does not seem to be in the registry)

This seemed to occur after I updated to FF 3.6.16

How can I identify the culprit? Thanks!

Eventually I came across a couple of posts where people have experienced this.

Creating a new profile corrects it, but you'd be wise to use the FEBE add-on to do a backup so you can rebuild your profile more easily.

Actually I had also tried FF4, then reverted.

It seems that installing FF4 can cause this problem, so some people may need to be beware of this.
