The author fixed a bug where I did not see the icon on the toolbar. It blocked sites for me, but I am using it in conjunction with PublicFox to lock my settings from being changed. PublicFox will not lock this since the settings are accessible in the toolbar. So I ended up using Simple Blocker, which worked to enforce a whitelist for me.
- Updated to pre-release versioning for clarity as I add more to this (not sure if there's an alpha tag or anything for add-ons) - Fixed an issue with the icon not being visible.
Updates to the list info is done through the toolbar icon.
