HOW TO USE Rated 5 out of 5 stars

Cool app, its launched through the Add-on bar, which I have turned off by default so it took me a bit to figure out how to start it..

Press Crtl + / on windows machines to view the add-on bar, the Lightbeam logo is in the far right corner. Click on it.

This review is for a previous version of the add-on (1.0.2.1-signed).
