FIREFOX IS KEEPING UP AN ADDON THAT GIVES PPL VIRUSES AND MALWARE!!!!!!!!!! STAY AWAY FROM THIS!!!!!!!!!

I have never written a review for an addon before, but I took time to do so today so you guys would STAY AWAY FROM THIS ADDON!!! All addons open a window to their site to say thanks for downloading and what not. So that was fine, but unlike most ppl I always check my cookies after that happens because I don't trust random sites. When I checked my cookies this addon's site added over 30 cookies from adware, porno(some disgustingly graphic), and illegal websites!!! This came from this site as they all appeared RIGHT after I opened this site, and before that the only site I had been on was Google and Youtube for the whole day....the fact Firefox is keeping this up even when other reviewers have pointed this out, is disgusting.
