Breaches privacy and allows unsafe sights to pay money to show up as reputable. It's been removed previously by Firefox for security threats and privacy disregard. THEY WILL SEE YOUR DATA TO ANYONE AND REMOTE EXECUTION CODES HAVE BEEN EXPLOITED FROM THIS EXTENSION. Hilarious how a service can offer privacy features, yet exploit your privacy instead. This should be illegal, but it's owned by Facebook so money blocks any penalty. 0/5, and anyone rating higher must not know of the terrible breaches of privacy this extension has caused.
