I have recently started work on a xpcom component for Firefox,
astonished i was by the fact that in an XPI archive file one can
include binary libraries (dll/so files) that get auto loaded in
firefox via a precise function prototype. The problem is that the code
in that component is allowed to do anything the user that runs firefox
has credentials to do.
Wham i am curious is if there have ever been reported malicious
mozilla extensions, and if besides the signing of the addon is there
any other way to protect from such addons.

I vaguely recall this in March:

and, more recently, there was a big deal made of issues with teh
updgrade mechanism:

I'm sure there are better links for these issues but these are what
came up in my traditional 20 seconds of search term creation.  :-)
