I first encountered BlockTube a month ago when its creator posted it on /r/firefox. It was then in beta and some of its functionality was limited to regular expressions—something that has since been much improved with a new UI. Now many of YouTube's annoyances can be fixed without hassle. Front page auto-generated playlists can be permanently removed through a checkbox and clickbait titles can be filtered by adding keywords.

BlockTube's “Block Video” and “Block Channel” features are so seamlessly integrated that I initially thought that they were added by Youtube themselves. Excellent!
