I've been using this combination. I first started to use Abine DoNotTrackMe (I think it actually came out first. I do not recall.). I started to use AVG Do Not Track, because I wanted to keep up with its development. Currently, Abine DoNotTrackMe blocks 227 trackers/others and AVG Do Not Track blocks 40 , which equals a total of 267. We're dealing with a difference of 187. I always thought it were a bit redundant to have both, but it turns out that AVG Do Not Track actually blocks 19 17 trackers/other that Abine extension/plugin does not. Not that much, but still a few that Abine still does not block. I'm going to check other extensions, and see if any of them would block more trackers, or if they'd be 100% redundant. For now, I'm keeping both extensions, as AVG's one still has some use. -edit- The numbers differ by small amount, because Abine calls Twitter addon Twitter Badge, while AVG calls it Twitter Button, and the same happens to Facebook. So, we just need to remove 2 from the 19. From what I could see this is the only difference in the names; I couldn't spot any others.
