NetPositive 3.0d3’s HTML filtering capabilities allow you to filter banner ads from pages that you view. To set it up, every time you see an ad image in a page, right-click on the image and choose „Filter this image in all sites“ from the „Filters“ submenu. Then, open up the ~/config/settings/NetPositive/Filters folder in the Tracker and edit the filter string down to the minimum sensible string that will generate a hit for the ad banner. (It’s best to look for strings like ‚/ads/‘ and such in the img src attribute). With a handful of these filters in place, you will see very few banner ads while browsing.
