Finally found a downloader that will allow the download of age-restricted videos.

needs PRO to download mp3

Seit Jahren gepflegt und ein sehr nette(r) Entwickler(in).
Hält was es verspricht!!! Danke Dishita :)

this is a super easy to use app. offers multiple formats (depending on what YT offers...he can't create HD video from low res uploads. YT also changes the algorithm regualrly but the developer seems to quickly update the software to deal with it. Best donation Ive made for freeware in a long time! six stars!

A simple extension that does exactly what it says on the tin. Thank you, Dishita!

nie działa , nie reaguje na przycisk DOWNLOAD :(

It's great for most videos, but doesn't work for age-restricted videos. I'd suggest building some add-on to the extension that reads your google account to verify age, and allows for download.
