I use RequestPolicy every day. I'm amazed that no browser provides this functionality built-in. Blocking all third party resources by default offers some strong protection against XSS and tracking sites. That it blocks ads and causes pages to render more spartanly is merely a bonus and exposes poor designs. Since everything that's blocked is accessible with the click of a button, I don't find it that inconvenient. I just wish more sites would serve all of their content from within their domain (including ads).
