I was considering a donation (I did one for ABP a week ago), but not anymore. I'm also glad I had not donated yet. The latest version (2.0.122) removed blocking ads in YouTube for no good reason. The author says that his ad-blocking system "became useless anyway", but it was actually WORKING. Ads started appearing immediately after the automatic update. This is not Chrome, this is Firefox. What constrains the author to obey Google's rules in a non-Google environment? I'm really curious about what happened behind the scenes.
