Rated 1 out of 5 stars

Worthless. Not worth a fraction of a star
Even worse, dishonest and misleading. Does nothing unless you are registered user, in contravention of the add-ons description. Even then, what it does is not what it claims to. All it can do, is search the storage site.

It might have some bugs, it hasn't been updated in a long time, but it does work actually, registration is required due to abuse, we wouldn't ask for it otherwise!
