Maybe this was good at one point, but it's complete trash now. You basically can't use the free tier.

Terrible plugin, author stated it's free but it's not. He coded spam tab in the plugin and it pops up every several hours. Author constantly alter the pro version rules and force you to donate again by invalidate your already donated "one-time donation gets lifetime subscription" pro verison.

DON'T DONATE, don't encourage him. There are plenty of youtube download software providing much better download experience with lifetime license or yearly subscription at similar cost, but much better experience, buy those!

Doesn't work

Garbage Free Version

garbage addon that only downloads the worse possible quality without paying for PRO version.

Doesn't work

Only works if you pay for a pro account...

Can't do HD, and too slow...not working

You have to buy this product to get anything but the lowest quality video. That sucks considering the fact that they already upload your personal data. So basically you are paying them to give them ad revenue and you are paying them to sell your personal data. Run like the wind. This is garbage.

Nothing. Just NOTHING. WTF did these db's just do, put crap on my system?

the green button is not appearing for Firefox on Ubuntu 18.04

This "recommended" addon won't even let me download vid as audio and pops some HD vid limitation warning while I only want to download mp3 with lousy 128 bitrate.

Generic Youtube videos download fine, but movies don't, and I mean FREE movies; audio files can be downloaded, but not MP4 files. JDownloader works fine, why can't this extension?

NOT FREE
