WebBlock

Started spam-blocking upon start-up, closing Chrome as soon as I clicked anywhere on the screen. Worked fine before that, but the 'click anywhere and the blocked tab closes' was pretty annoying even then.

great. works as advertized.

Good Extension. Does not sends data to somewhere. Clean Extension.

Awesome extension. Please add support for Firefox asap!

Great tiny little web blocking extension. Loads really quickly and yet has enough functionality to be tremendously useful. Give it a shot.
