You have a green Adblock icon? Mine vanished a few months ago, just about the time Adblock stopped working. Adblock still doesn't work (and no green icon) and I have the newest Version 90.1.9508.213 (Official Build) (64-bit) of Avast Secure Browser.
YES, Adblock's turned on. YES, I've played with all the settings levels trying to find one that works. NO, none of the levels make any difference in blocking ads.
Stuff's piling up for me, Avast people: No Video Downloader (YES, it's turned on); no Adblock or even an icon for it (YES, it's turned on); no Translate function (don't know where to turn it on); messed-up, constantly changing icons of essential sites on landing screen with 1 slot I can't use. Starting to wonder why I pay for Avast Premium, seems I could get all this aggravation for free. LOL
