Hey HN, I auto-play music using the YouTube mixes a lot but occasionally certain artists are put into the mix that I no longer support. Being tired of racing back to skip a song and noticing the lack of ability to remove videos from private mode, I created TubeSkip!TubeSkip is a simple Firefox addon that will skip any videos containing a keyword on the addon's list.
MIT License and welcome contributions to fix Chrome, most of the addon works there but it does not skip the same as FF.
