Exactly what I was looking for Rated 5 out of 5 stars

Thanks for developing this.
I had been using my WebShield feature in Avast (virus protection and removal) and it worked well, but I wanted quicker access to add sites to a block list and this add-on is perfect.

Users should note that they should include a * at the end of the URL that they want to block or they'll find that the site doesn't get blocked.

This review is for a previous version of the add-on (0.7.1).
