Hi, I have been using the Ultra surf proxy add on now in Mozilla Firefox for a while now, with no issues or problems. But this morning when I went to use Firefox (my go to browser) it said that it had been disabled a removed from my browser, as it didn't have a verified certificate for use, witch is fair enough.. But my problem is now that the add on it self when it was removed by Firefox, was still enabled in proxy mode in my browser, meaning I can't use my browser now without having the Ultra surf proxy running in the background, as I never got the chance to disable the Ultra surf add on itself in Firefox before it was removed.. I have tried to install the Ultra Surf add on again so I can disable it manually myself, so I can go back to using my browser normally without the proxy enabled but Firefox won't let me install it.. So I'm now stuck in ultra Surf proxy mode with Firefox, As I never got the chance to disable the add on from proxy mode myself before it was removed.. I don't Know what to do Now, I tried to uninstall then reinstall Firefox but with no luck.
