Rated 3 out of 5 stars

NoScript does a great job of blocking everything, but if you don't want to block everything, configuring it is a royal PITA.

I highly recommend Karma Blocker. Much smaller and lighter, and with a little tweaking it can provide almost as much protection as NoScript without the annoyance of overprotection (blocking everything).

This review is for a previous version of the add-on (1.8.5).
