Perhaps it’s because I never raw dog the web, and using uBlock Origins on “medium mode” somehow fixes this, but I don’t think I have ever experienced this.

I have experienced sites that block right clicking, and that has always infuriated me. But I was able to get a little FF extension that disables right click blocking on websites. Which is pretty useful for downloading videos on sites that try to stop you from downloading their videos (though some have wisened up and can completely disable the ability to save a video through that method. The “save video as” option is completely greyed out. yt-dlp usually works in those cases, or one of the countless web-based video downloaders… but still annoying.
