Last update was over 8 months ago, since than a few features stopped working. Blocked channels and the option to block works in home page but not in video sidebar. Some random select videos are blocked no matter what and can't be unblocked. Works fine otherwise but those 2 issues are really big annoyances.
edit: Sept 15, 2025 update fixed my complaints :)

Has stopped working, and hasn't been updated in the past 7 months.

it has stopped working for some reason

Please fix!! Needs to be updated. When using this extension and loading a video on YouTube, it just closes and sends you back to the homepage, making it impossible to use. Likely a problem with YouTube in general, but this needs to be fixed.

Otherwise an awesome extension when it works; it lets you block out the annoying content you hate seeing, and makes sure you never see it again. Please update this so I can change the review to 5 stars like it deserves!

It works fine, but sometimes the context menu disappears. Refreshing Youtube pages often does not restore it, and instead a full restart of the browser is required. Other than that everything's gravy.

(note: this review is heavily altered from its original state, it was initially a two-star complaining about the context menu disappearance, but now that it's come back after a fix on my end I figured it was unfair to leave the review and rating as is)

EDIT: Never mind again, back to two stars as the context menu no longer appears on videos in the "recommended" sidebar on a video page despite it appearing on videos in my history. Please fix this.

2025.07.31 It doesn't work. Developers should respond immediately, or Firefox should stop providing add-ons right away.

Love it! A block feature on Youtube just seems like such a no brainer I consider it practically malicious that it's not an inherent feature, however this extension works wonderfully and I appreciate the option to have something ACTUALLY not recommended or to block particular videos over the whole channel. I downloaded it for that one initial purpose so I hadn't read the full list of features and was very pleasantly surprised to see that I could disable Youtube shorts (the second biggest bane of my existence) as well :)

Very useful plugin to make YT bearable again. Thank you!

Just works. There is no higher praise than that.

It used to block Playlists from searches, but it no longer does, hopefully this gets fixed. Thanks for the add-on by the way

easy to use.
but sometimes this interfares with playing videos. (especially in shorts)

Nice Addons
