Rated 4 out of 5 stars

Would be better if the window was resizeable. Reply: Tried that, didn't work. I assume there's some conflict with another add-on I'm using, but pretty weird. Other add-ons have resizeable settings windows. Anyway thanks for your work!

This review is for a previous version of the add-on (2016.2). 

A previous user had a problem with the setting window not being resizeable. It should be. They wound up fixing it by restarting their computer and restarting Firefox.
