Love it. Rated 5 out of 5 stars

This add-on blocks all third-party requests (html, scripts, images, etc.) by default until you manually allow them on per-server basis, either temporarily or permanently. If you're tech-savvy enough to understand what that last sentence means then you'll have no trouble understanding how to use this add-on after trying it out on a few sites. It's very similar to NoScript, but is not limited to scripts / plug-in content.

This review is for a previous version of the add-on (0.5.25).
