Doesn't Adblock Plus alter the structure of the page, which can mess up layout? Also believe it or not I don't want to block all ads, just animated ones.

I want something browser makers can build in and turn on by default, which is what Safari has essentially done now with Mavericks (Flash and Java are blocked by default.. Flash under the rubric of power conservation).
