Be aware that anything which triggers a repair of the .NET framework will
probably restore the key. This might (I don't know) include things like future
..NET updates, or the installation of new programs which use .NET.
Hopefully a future version of Firefox will require global add-ons to be opted-in
by the user. I think that would be the best long-term solution.
