After many months without a problem, suddenly icon is nowhere to be found, thus it can't be used. Rated 1 out of 5 stars
Version 2.55.2 icon does not appear on the browser nor is it in the customize section.
Pity, prior to this incident, this was the easiest, reliable, stable, best all around screen capture Firefox add-on I have ever used.
This should be a core feature of Firefox.
Sorry about the bug, we're working on a fix and will submit it for update ASAP.
