You can only ALTER, but not ADD shortcuts... Rated 4 out of 5 stars

Its only possible to change/alter *existing* shortcuts, ff offers.Its *not* possible to create new ones, if the user is missing essential shortcuts this addon cannot help.A pitty :-)

as long, as you don't need any new shortcuts, this addons works good.

This review is for a previous version of the add-on (0.5.11.1.1-signed).
