Simply mandatory ! ^^

This is a wonderful app. I commend the programmer. Very useful, does what it is supposed to, no annoying ads, and well maintained. I consider this a requirement from my browser. Well done sir.

I am so glad to see that this one is back, because of the ease and speed difference. I Missed it!

Simply terrific

fantastico

Works very well and very fast to update when YouTube changes their code. Well done.

A very easy to use and convenient addon, and the developer is quick to adapt to any changes that YouTube makes with their layout.

I have used this addon successfully for years... reliable and easy to use!

Excellent !

Legendary app. Thanks so much for this.

does what it says on the tin, it works, it integrates fairly alright into the youtube UI, and it displays the video size before downloading the video itself
