Update 30th July 2026 - Does now remove "members first" videos - videos that can only be viewed by members and will later be available to non members. These "members first" videos are just as annoying as the "members only" videos.
Update 31st July. Odd behaviour. Example - Youtube is trying to put a members only video as second in the list on right hand side. This add-on has removed it. If I mouse over the first video in the list, it is still hidden but if I mouse over the second video, that changes to the members only video. Mousing over any videos below the second also brings back the members only in second place.

The only one that worked!

That’s what I’ve been looking for for a while, and it seems to be working quite well

Does not work at all.

Doesn't work for me at all. The 'members only' videos still persist.
