Update April 2026: This remains my most useful extension after Adblock. Dishita has kept his product up-to-date for years, and it continues to serve. It still works great and is easy to use and to date has never failed. Right now it appears we are in another period of YT blocking it, but I have faith that Dishita will continue to jump their hurdles. many thanks, Dishita!
Update 8/26/25: Dishita continues his amazing work, maintaining a truly 5-star product that keeps on working despite the ever-growing strength of the adversary. This is one of the few "must-haves" out there; for this job there's nothing that compares with it. Thanks, man!
Update 7/14/21: the developer stays on top of YT code changes, which are made periodically to interfere with products such as this. When that happens it is a brief inconvenience but the guy soon handles it. Great maintenance. he's good. I wish he would make a general downloader as well
