Rated 3 out of 5 stars

Great idea! However, it can be hacked. Since you don't have to authenticate with the 'dislike server' (it's not on Facebook) you can dislike things as other people.

Also, the undislike feature doesn't work for me.

This review is for a previous version of the add-on (0.2). 

Fixed

The undislike feature is fixed. :)

I will add cheating protection in the future. :)
