[fedora-india] addon for firefox that takes a back up of other installed firefox add-ons

[Debjit Saha]

The subject must have made it all clear. Does there exist any such
add-on which will take a back up of all currently installed add-ons on
my firefox browser? This is really required because once we re-install
an OS all the add-on settings are lost and re-installin all the
add-ons again one-by-one is really a pain
