About this Add-on
- First, every site you visit is matched against a database of 200+ known rickroll pages.
- The second level of protection is applied to all Youtube videos: the entire page is searched for suspicious keywords, and RickRemoval prevents it from loading if it finds too many warning signs.
Together, RickRemoval's comprehensive blacklist and heuristic analysis make it all but impossible for you to ever be rickrolled again.
