Rated 4 out of 5 stars
The addon itself works great. As it is a thorn in the eyes of the content mafiaa, I am glad to have it and hope that I'll never actually need it. (5 stars)
However the fact that simple xml lists seem to determine which sites get redircted where poses a security weakspot for the addon and should be changed. (-1 star)
Thanks for the review and your concern is duly noted, we are working on a solution that will be implemented in the next 3 or so updates...
EDIT: Fixed in the new version! (0.6b)
