Works perfectly for me. I don't know what the bad reviews are for. I liked it enough to upgrade to the Pro version. If you use it a lot to study tutorials, etc. it is worth it, whether you use the free or Pro version. (Other extentions I've tried were much slower and buggy and often fail altogether.)

It has been a great tool for years and kept up with the changes. It is more than worth supporting, I should have done that earlier. My bad.

Great app! Works every time! Few days of delay after Youtube/Firefix updates

Great add-on. For those who removed it or rated it very low: it rarely happens that the add-on may not work for a couple of days, but the occasional problems were always solved. I am very satisfied and will continue supporting it.

Excellent. Excellent add-on for regular youtube users. The fee for downloading high-res videos is nominal and the service is super! Thanks guys! you are doing a great job.

I use Youtube extensively. I have been using the Pro version for some time. Very satisfied with the same. Highly recommended.

nice app

Downloaded a very long video with no problems and good quality.

First rate downloader tool. Thank you.
