See ads recently even though you use AdBlock?
So AdBlock recently (late Dec.) came out with the option to allow for "non intrusive ads". It hasn't really been a big deal for me at least, but they've slowly increased the number of ad providers who are approved and recently approved a lot of advertising on twitch.tv and own3d.tv. If you start to notice ads where you don't want them, you can turn all them off by:
-- Clicking ABP icon
-- Click Filter Preferences
-- Unclick the "Allow some non-intrusive advertising" checkbox
I understand their decision to do this, but wish they would have left it to me to disable ad block on sites where I wanted ads (like n00bfest.com).
Anyway, more info
here if you're interested.
