Video Blocker allows you to hide videos from channels that you don’t like. You can specify these channels by right-clicking on a link to a video on YouTube or by adding them manually via the options page. You can also hide videos from multiple channels at once, by using a wildcard or adding regular expressions. Blocking videos with certain keywords in their title is also possible! Comments will also be blocked the same way as channels. For more information on how to do this exactly, please visit the help section at the settings after installing this extension. Every item you add to your block-list can now also be protected with a password!
If you find any bugs or have any other problems with this extension, please notify me via the support option on the details-tab on this page. It is very difficult to help you out if you report a problem via the comments, since there is no way for me to respond to you.
Good luck and happy video blocking!
