webrep on firefox mac canot unistall

Hi Guys, I installed this soft really I don’t know when in the past , but was a lot time ago probably more than 2 years ago. Since them I’ve been using another antivirus in my mac, just probably a year ago I noticed that I still have this particular plugin (webrep) that I cannot uninstall because is not part of firefox, yes of course I could disable and in fact is the way it is. To have my firefox clean I tried many different things.

-uninstalled firefox 3 times completely (didn’t pan out)

  • looking where is finder ( I couldn’t find it)
  • downloaded avast software and uninstalled , reboot , etc ( the extension remain there in my firefox)
    -I tried to install vast with the idea to uninstall this annoying addon (unfortunately I couldn’t because I have another antivirus in my mac)
  • I called 3 times to avast support, talking whith different agents (nothing)

If anyone knows could you guide me to solve this and uninstall forever this addon in my firefox?

THANKS GUYS
