the extension has worked perfectly for many months. now the adblocker setting resets to off on its own every hour or so. I leave the adguard window open in another tab so that i can constantly monitor it and turn the blocker back on. using with Firefox 18.5.0.0 and after reading many of the latest reviews here i am guessing that I am not the only one dealing with this. hope you guys can get this bug fixed so that I can return here and give you a 5 star rating!
