Downloading Videos REGARDLESS Of What Google Wants

[osminogig]

Is the downloaded files size normal?
Have you installed the codec of PotPlayer?

Yes, the file size is normal.
Yes, it was in the player, I downloaded a fresh one - it works.
Thanks for the help and the best browser !

I will still use third-party programs, because:
Much faster download speed
Only audio can be downloaded
You can choose the quality
YT-downloader has a floating window - you can quickly download a bunch of videos
Etc..
