Yes, I have been using Palemoon & uBlock Origin for a long time and it works well. But there is a problem that has nothing to do with the filters. YouTube has started throwing up messages that adblockers are not allowed. But I don't get that when using Firefox or Chrome with a newer version of uBO.Making sure you keep your filters up to date is more important than how old the extension itself is. I use the uBo extension you mentioned, and it works just fine.
That's why I asked my original question. It seems pretty obvious that the newer versions of uBO have made changes to compensate for YouTube trying to ban adblockers. That's why it is important to have an updated program, not just an updated filter list.
