CloseReview for RequestPolicy by Spinfx
Rated 5 out of 5 stars
Agreed with most of the others - this is an excellent tool, and yes, adding a blacklist will be helpful as well.
I tried NoScript back in the day but it was too terse/cryptic for me - I love Request Policy's simple dropdown list of sites style. Not to mention apparently NoScript and others don't actually stop the browser from connecting to the ad servers, they simply don't run the scripts there - but the ad server would've already had your IP. Request Policy blocks all connections that aren't allowed, period. Surfing is way faster now.
