For the longest time this was my "go to" down-loader. Then Mozilla kept messing with it and disabling it. I tried other down-loaders but none of them worked as well. I had to use another extension to get high quality down-loads, but none of them are as simple to use as this one. I'm back to try it again.
I miss not being to download 720 and higher videos so I hope Easy YouTube has come to my rescue once more.
