Скачивает видео быстро в любом качестве на ПК

Exactly what I was looking for!

Excellent!

It's free, it's not nagware, it can download audio or full HD video, and it works (at the moment), so what more can you ask for?
Note that to download video with audio, click on a "video-only" option with ffmpeg installed, and the video will be merged with the audio when finished. Installing ffmpeg correctly was a bit finicky though. And audio files downloaded without ffmpeg wont play on my phone. Download speed for audio is kinda slow, but it's much faster for HD video.
Great to see it working again!

1.2.1
It works fine. Thank you for the wonderful work.

As of 1.2.1 problems seem to be fixed and it works OK.

Very good function of this addon. And especially now where the adjustments to new versions of Firefox happen quite quick.

Just the speeds of the Downloads are extremely low, like 1MBit/s. Is that due to the Native Client or can I fix something?

**UPDATE**Firefox 97.0.0 YD 1.2.1 is WORKING
Please Respect the Developer and STOP COMPLAINING. IT IS a FREE EXTENSION
YT changes their codes frequently and did mess up this extension and is no fault of the developer.
This is the best YT downloader I've ever tried
If it stop working again, try downgrade to a lower version and WAIT for the developer to find a fix.

Funciona perfecto con Firefox 96.0.3 (YD 1.1.7.2)
El mejor downloader de este planeta. Y probablemente el mejor de este Sistema Solar :-)
