The latest version AdBlock Plus (version 2.0) includes a whitelist of "acceptable" advertisers that by default overrides your blacklist and filter subscriptions. These "acceptable" advertisers have signed contracts with the AdBlock Plus author, who says in his forum that he is hoping to make money on this feature.
"Acceptable" ads include those which use third-party scripts and plant tracking cookies, meaning you could be subject to a drive-by malware attack or your privacy could be compromised using the default installation of AdBlock Plus.
I've been using this extension for years, but I will be abandoning it as soon as a fork appears or different adblocking extension is released. I don't like the idea of a third-party deciding which ads are "acceptable" for me, and putting my system and my privacy at risk.
