Many thanks to Dishita for his great work and recommendation to try the beta version of the desktop app, since the add-on was banned from YT a month ago.
I didn't use all the features yet, but the desktop app seems to work fine on my Mac, no issue encountered so far.
I would like also to underline that the add-on was working good with Firefox as well until it was banned from YT, no matter if you made donation or not.
I'm looking forward to the official release of the desktop app.

A few words to the users who are blaming Dishita that the add-on doesn't work.
TRY THE DESKTOP APP

The best for downloading YouTube products

Well it was worth the wait as now that the bugs have been cleaned out the interface works seamlessly on Windows10 and is a reliable and fast add on to use.

The latest version of the Downloader works very well. Well done! The Support team is also very responsive and helpful. Highly recommended!

Is very nice extension, i love it and is workng perfectly on My MX Linux 23,4 x64 Libretto XFCE, operating system, i have follow the instruction of the MX Linux website for install the AppImage program for Linux and is working.

Is working nice for the Windows user to, but me i am only on Linux, Windows is end for me, to much problem with Windows system, Linux is better, no virus, no need to pay a licence for the operating system and the programs, all is avalable for free, no file lock problem, nothing of that.

Only open source and free and very nice stuff.

Windows = 0 And Linux = 1

For this extension, and the desktop program version, the desktop version is working better, the extension is bug and stop to working to appear the download option, but the desktop version is working nice with all public vesion of the video, but for the private video, i have tery to connect to my youtube account and try the trick of the cookie for unlock the access to download private and restricted video and is not working, i don't know what i need for make this working for me.

And another last thing, i don't know what is me Pro key for the activate the pro version of the desktop program, because, the developper i never send me in email me key for the program, i am pay $43,82 CAD - $30,00 USD for buy one pro licence key for me and i am never recive in email my pro key, i have pay ad i not have me key, is not good and is not correct.

To the developer of this extension and this desktop program, send me me valid pro key for activate the pro version of the full version of the next updated full version of the program, i have pay for that, i need it.

This is a great app. I've been using it's predecessor for years. Even in Beta, the new version works flawlessly. The few times I've needed customer support responses have been fast and my problems have always been solved.

Works as it should and the developer is very responsive. I no longer have to sit in front on a screen downloading files one at a time. Totally worth it.

Goody in my book of extension life.

I've been using this amazing extension for a big time and it have helped me a lot downloading videos! The best choice!
