Where are my Iceweasel extensions?

[Mitja Podreka <mitja.podreka@gmail.com>]

Hello

Few days ago I've upgraded to Iceweasel-2.0.0.4-0etch1 and all my 
extensions (except DOM inspector which is installed as Debian package) 
disappeared. The files are still in extensions folder, just Iceweasel 
ignores them.

Also had problems with upgrade to Icedove version 1.5.0.12 (20070607). 
After the  first start of the upgraded Icedove the program downloaded 
again all the mails from some of my accounts.

regards,
Mitja
