Hi, Does the firefox extension work like ABP? Meaning does the browser download everything (ads and all) and then ABP removes them before allowing the browser to render the page? Doing so doesn't really save any bandwidth or security (web bugs etc. still report that it was downloaded). Or does it work at the network level, intercepting any requests/calls to blocked sites (bandwidth not wasted and the request never makes it past your machine)? Thanks for making a nice program.
