This seems to be happening to any browsers with the string "AppleWebKit" in their user agent. You are probably using Google Chrome, or Epiphany on Liberte. You *should* be using the TorBrowser only for many reasons: https://www.torproject.org/projects/torbrowser/design/ But if for some reason you don't mind compromising your anonymity, you could simply remove AppleWebKit from your user agent, and/or change it to the Tor Browser user agent.
