I'd like to give it 5 stars, but all too frequently the ad blocking interferes with many websites functioning properly; i.e. such as contact forms. It also has difficulty blocking on my Yahoo mail's inbox. There is a banner which sits above my incoming inbox emails and it looks like the first email (which makes me click on it) but it is actually an ad. Sometimes Ad Blockers blocks this area effectively, but I notice that the ad will override and reappear. At that point I disable and re-enable to make this ribbon ad disappear. I hope they're listening! This ad block service claims to be "fighting the anti-adblocker messages some websites show when they detect the use of one". This feature doesn't seem to be working since I constantly see the message which tells me the website know I'm using an ad blocker and that I turn it off.
