This is fabulous add-on!
Very easy to use.

Easy install, works fast, no glitches, various high quality formats, a few "download this" popups, but no malware like the numerous bogus online services. Overall great! Thank you!

superb

Ignore all the idiots who just love to complain. This is a brilliant add-on. I need to download certain vids for educational purposes and quite often such videos when studied require a lot of replay, speed up/down and skipping back and forth. These are best done on a standalone player and not in a browser. Thank you.
