Where is it? Rated 1 out of 5 stars

I installed this on FireFox 31.0 (what a horrid piece of crap) ... it said it installed it, but it's no in my Add-Ons or anywhere else to be found. Screenshots are swell, but useless if you don't include basic instructions for invoking the thing.

This review is for a previous version of the add-on (0.6.6.1-signed).
