a fancy little (and highly customizable) web filtering program. i love it. it cuts out most ads and replaces them with the alt text, and i never get things dancing across my screen. the internet is getting out of control, so i put my foot down.
it's a little more than most people want to do probably, but it also has a convenient 'bypass' switch. i use that when i want to rate netflix movies, and that's pretty much it.
