Rated 2 out of 5 stars

This is a GREAT idea and will catch on quickly, EXCEPT that it makes the browser run EXTREMELY slow. By slow I mean every other second it completely freezes everything for about half a second. This gets extremely aggravating very quickly. Typing is made much slower, as well as corrections to typing. Other flaws that may or may not have been mentioned are that it CAN be hacked (you can "dislike" as other people), it doesn't show up in notifications (the red flag in the bottom right when someone has commented or liked a post you've made). So, I'm telling all my friends, but I'm disabling the feature myself (for now). Fix the bugs and this will get Explorer people to switch to Firefox, guaranteed.

This review is for a previous version of the add-on (0.2.1).
