Rated 4 out of 5 stars

Love this simple add-on for what it does. Needs 2 improvements:
- The icon is ugly as sin! How about something like a simple round red/green circle (flat or 3D) to indicate site blacklisted (red) or whitelisted (green)?
- Needs some sort of a back-up and restore feature of user created blacklists so its easier to re-install on other machines or do a local restore if needed. This is a must!

After this, 5 stars! Keep up the great work!

This review is for a previous version of the add-on (2.1.1-signed.1-signed).
