Sad, but necessary Rated 5 out of 5 stars

Trueblock Plus is the same code as AdBlock Plus (which is open source) except with the "acceptable ads" feature OFF by default.

Now that the original (and, up until recently, very awesome) AdBlock Plus extension has, by default, added a whitelist of "acceptable" advertisers that overrides my blacklist and filter subscription(s)-- potentially exposing me to malicious scripts and tracking cookies-- a fork was, sadly, necessary.
