I was able to download videos but twice it download the previous video instead of the one I selected. Hope you are working on this and solve it soon. we can't know it's wrong until download is finished.

This helped me load a large video without any crashes to the desktop.

On one hand, the extension is finally working after a long revision time.
On the other hand, its local in-browser process is way too hungry, leading to freezes and crashes of Firefox thanks to an overconsumption of memory.

Working again. Kudos to the heroic developer!

Wow it works again!

I would rate this higher if I could!

Long history of great work with this add-on. Occasional downtime and issues due to counter-development by you-tube. Currently the icon doesn't work and sometimes there are multiple "Download As" buttons but these are just aesthetic issues. Highly recommended!!

I have had issues with the interface until recently, but right now, the current changes are really well-executed and it seems flawless. Waiting to see whether it stays this way...

THE BEST

I've used a lot of video downloaders with varying degrees of success. This is by far the best one I've ever used.
