I had AdBlocker without any problems for ages, but one day it just vanished. As in, it goes from working with its little icon in the browser, to just being absent, no notifications, no icon and of course no ads being blocked, and checking my add-ons etc shows me I have no AdBlock at all. I checked your forums and read to delete the extension files in case they're corrupted, so I did that, but nothing is fixed, my next few copies of AdBlocker vanished too. (After I found it gone the first time, I downloaded AdBlocker Edge 2.1.6, instead of the usual AdBlocker, so that's what I've been using... But every time, the next day it's gone too. This is the third time I have downloaded this AdBlocker in as many days.) I've been checking while I browse to see where it vanishes, but I can't see it happen, as far as I can tell it vanishes around shut down or start up, not while the browser is open. I've tried opening and closing the browser but AdBlocker stays put, only when I turn the computer off does it somehow vanish before next use. Any ideas? Thanks for your time.
