Rated 5 out of 5 stars
Essential part of my web security. Allows me to choose which cross-site requests are permitted (and makes me wonder sometimes why these webmasters think they need to connect to so many other sites!) Doesn't interfere with NoScript specifically, but allowing scripts from the site is not the same as allowing connection to that site. To enable both, you have to choose both, but it doesn't seem to matter whether you enable scripts first or cross-site first. One of the first plugins I add to any new installation of Firefox.
