Does not work Rated 1 out of 5 stars

I installed this add on twice, despite the browser not needing to be restarted . I tried to do this in case it helped. but no dislike button appears on any of the face book pages. I even restarted the laptop. logged in/out facebook but nothing, does not function. I use Aurora if this helps

This review is for a previous version of the add-on (3.2.1).
