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.

does what its supposed to do

Very easy to use and excellent downloader

this is the best addon to download youtube videos

Great add-on! A must have for anyone wanting to download YouTube videos.

This is very convenient and useful. Time saving. Up to now, only one shortcoming was found. Certain download options need additional download and installation of a 3rd party plug-in, which is not convenient for users without installation authorization.

new version(v18.3)works very well, it helps me a lot. thanks Dishita
