(Version 0.4.4, w/ FF132.0.2) WORKING FINE since released.
It is a MUST add-on for FF browsing YouTube.
Thanks to developer for all the hard work.
Moreover, is it possible to add a custom feature for the context menu as I only use the "Block Channel" and would like to HIDE the "Block Video" key.

Absolutely goated addon, very useful!

It was working like yesterday but for some reason it doesn't work today. I don't know if it is something to do with my computer or youtube but it looks like other extensions on youtube aren't working anymore.

An absolute blessing! Just getting rid of Pegasus and his clickbait alone makes this addon incredibly useful!

Does not work on Android Firefox anymore, channels I just blocked show up the next time I click a video or refresh the page. Please please fix!!!

Add-on doesn't work at all anymore. Channels in my block list are not blocked. Shorts are not blocked. Any code I write in Advanced Blocking is just not run whatsoever.

Addon still works.
The button to block a channels stopped working.
BUT you can still manually add channels you want to block in the addon settings!

siiiiii

Had a great experience with this add-on. Would really like it if there was a way to block Short channels. Not ALL shorts, just channels like the normal videos. Fingers crossed that comes in the future! I've blocked so many channels though and it's made my yt so much better.

Good for blocking videos that I keep getting that I don't want to watch, though it would be nice if there was a setting that would still allow you to see the videos in search.

It was nice when it worked, but now it doesn't.

Just installed and looks good so far except it's blocking videos that I didn't not flag to be blocked.

Feature request: an option to block "includes paid promotion" videos too.

Addon is great when it works properly, and still works quite well now if you're patient with it. However, a recent update has rendered the standard block process useless, as the usual 3 dots to block function doesn't block either the video or creator anymore. You can still use the name of a video or creator, and it blocks just fine though.

Excellent extension. The only way to block stupid videos from YouTube.

it was amazing but it stopped working :( will give better score again if fixed

This does not work. It used to work fine. It no longer works, it blocks nothing. Kind of useless.

A strange bug: after one day of working, YT suddenly recognizes it as an unwanted adblocker and disables playback, you have to remove cookies both from google.* and youtube.com. Also, the Block video option from the 3-dot menu seems to not hide a video.

Like I said - I am changing it back to 5 stars because it is working again. And it is AMAZING add-on, essential for me. Shields me from stuff I do not want to see ever again. Thank you!
