This Extensions is amazing!
The author of this Extensions is truly outstanding and talented. After trying it, I found it incredibly convenient and easy to use. I immediately sponsored an upgrade, and the upgraded software is even more powerful. It can also download Facebook videos, which is very useful. The author is also a very nice person; he was happy to answer any questions I had while using it. I highly recommend this program and hope the author will continue to develop and update it.

Yooo, this one is the greatest add-on for those who wanna save and listen to some custom music in their games, on parties(when got no internet), etc.
I'm an example of who saving music to files, but I can't even afford the YT premium to get some functions (due to Russia's law and non-law acts made by RKN). This add-on is the lifeboat for me.

The BEST add-on EVER MADE- Thank you

Just great

This is my favorite video download utility, because it never fails and produces great standalone videos with no internet connection needed after the download!

Super extension, quick convert to mp3, good quality, very easy.
