Rated 4 out of 5 stars

Works great on sites such as Digg, makes surfing the web alot easier. It used to work on Reddit, however after formatting my computer and reinstalling everything, it no longer works on Reddit.

This review is for a previous version of the add-on (0.2.0.26). 

You can try to update the setting online again.
Some time the setting will not be update correctly for network issues or the update site down.
