Bug#648150: Addons installed as Debian packages show up as "third-party", and, 8.0 wants to disable them by default

[Timo Jyrinki]

Just FYI I noticed that Fedora is currently disabling this with the
following patch:

http://pkgs.fedoraproject.org/gitweb/?p=firefox.git;a=blob;f=firefox-8.0-enable-addons.patch;h=795b082e295f70b614743acbe0bbaf77a8b05288;hb=HEAD

I do also feel that Debian packaged extensions should be handled as
trusted instead of being disabled and considered somehow suspicious.

There is also a problem with the current approach that if there is a new
user created or an extension is installed as part of the Debian
installation, the user does not get any information about the extension
being there but disabled. This is the case in eg. Finnish installation
of Debian, which installs mozvoikko extension for spell-checking in
Mozilla products. For most non-technical people at least this means that
they just get no spell-checking, and for others as well some head
scratching in the form of "the package is installed but not working".
