SiteBlocker

When I add the url it didn't even block...

Works as it should and is effective. Minimal install and simple options. Thank you for producing such an effective and useful extension.

I love this extension, Can you add a new feature? as a request to remove a blocked website why not have a very annoying process to confirm that? for example: write a very long sentence, wait 5 minutes, etc thanks!!!

It doesn't work. It doesn't even have a place where you can add URLs or web addresses you wish to block. I would think that would be a basic feature for this extension.
