Absolutely Essential!

This is one of the best background URL blockers available, and I hope it gets updated to Manifest V3 so that it continues to be available. No other blocker (that I'm aware of) can be refreshed to show what URLs a site is loading in the background, and then let you block them - even using wild-cards. Allows one to clean up a lot of sites unwanted hidden URL loads - and makes things faster.

This extension does work you need to take out the first bit of the link for example www. http:// https:// and then paste the link or select it from the lists on the right. I've been using this extension for ages now and never had a problem its excellent at locking trackers, pop ups and redirects. It's a must have extension.

bloqueo un sitio y me sigue apareciendo en las busquedas de google, no hay tutorial en ningun lado :C

To those who say it doesn't work, it actually does and you just need to know how to. Just put something like "www.youtube.com" without the "https://" on the blocklist to get websites like YouTube blocked. You can also put "*.www.youtube.com" to make that site like YouTube as an exception from being blocked

Doesn't work

Is working perfectly for .zip and .mov domains!

Simple and effective, no complaints at all
