Rated 3 out of 5 stars

Pro: JavaScript is often abused, and this puts an end to a lot of those annoyances. Can't live without this.

Con: Firefox is secure. Most of this "security" stuff is hyped up and not really accurate. I use it for stopping annoyances, not for the "security" that if offers.

Con: Would be nice if there was a blacklist mode instead of being whitelist-only.
