HtmlFilter goes beyond traditional popup blockers by also blocking inline text ads served by major ad networks. This includes ads from Google, Yahoo! and MSN. HtmlFilter works with all sorts and web browsers and RSS clients. It installs on limited user rights environments. Popups, pop unders, inline ads, javascript, animations, transient ads, all are blocked. HtmlFilter goes even further by actually letting you replace referrers while you surf, thus making you more anonymous.
