no download. Why?

It doesn't work on region blocked videos. And since I had installed this extension solely for this purpose...

DOES NOT DO ANYTHING what it promises!!!
Exept it offers you the ProVersion which is a payed service!!!
PLS. WAIT, THIS CAN TAKE TIME... is the only thing it does!
HANDS OFF!!! I definetly will not recommend it, I don't know, why Firefox officially recommends it!!!
I personally miss the '0 Star' button!

As SOON as I paid for the PRO version it STOPPED WORKING.

DOES NOT WORK, I USE SMALLEST FILE, DOES NOT DL, I GET FAILED MESSAGE IN DL ICON WINDOW OVER AND OVER NO MATTER WHAT SIZE I PIC

i don't work anymore !!

Wont download hi res videos with out a lot of other software or paid version. There are extensions that will allow you to down load video and sound as two separate files. Look for those.

Simply useless.
This is a advertiser for a PRO-version only.

Turns out 720p is included in it's Pro.

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
