I don't use adblock, but I use NoScript. There are malicious sites out there, and NoScript has proven golden for me. NoScript DOES NOT block ads as long as they are not javascript-based. Personally, I don't want to support javascript ads that collect info. If someone wants to have an ad on his site, I would be glad to support him and even click the ad, but the ad must be PLAIN IMAGE with an A HREF link. Nothing else.
