You can only block channels that appear on your homepage, not on the fly as this claims. Which makes this pointless.

I have been using this extension (Chrome) for years. Very happy with it until today as it no longer works.

As far as I can tell it doesn't work. Wrote in "Linus Tech Tips" in the channel block field, didn't work so I added their channel ID in the corresponding field and that didn't work either. Still shows up in search results.

very first channel I added to the list is still coming through in the "related videos" side bar. This addon is crap.

Another one that does precisely NOTHING! It's NECESSARY to be able to block channels from the recommendations list with a single click - this won't achieve that! In fact, I can find to added menue to make it work AT ALL!

At this particular moment in time, June 2019, this add on does absolutely nothing. I guess it needs to be updated.

Doesn't work at all.

Trash blocker

I have never once got this software to block a single YouTube video & is completely useless. This app would have to get updated daily by the software company that designed & made it to keep up with YouTube & there constant updates. Don't waste your time on this worthless software unless the software designer starts updating there app daily.

Does not work.
