Fast, simple, troublefree MP4 downloader. Button shows in address bar on YT pages, it downloads the main video. Best out of several tried. Does what it says. Choose destination and available resolutions (sometimes more than 1080p, you can choose lower to save file size).
When subtitle download comes out it will be 10/5 stars.

Downloads in max resolution (1080p in my case) at a speed of 7mb/s. I do recommend it!

Huge thanks to the developers for a great extension! Is it possible to make the video download with subtitles?

I tried many such type of add-on & this one is the best by far, first of all it gives you the option to download on any resolution when some other I tried only gave option for lower than max resolution, also the download take full advantage of my connection speed & the download is super fast, I highly recommend it!

A really great Youtube Downloader!

GREAT download speed! Sooooo cool! Too many thanks to the author!

So far so good. I thought there was a problem with the very first video i tried to download. However, it looks like there is something blocking the add on from working on certain videos. It appears to prevent other downloaders from working as well on the same video so i can't fault this one.

App does what it needs to do, and developer is responsive to any issues regarding functionality.

Simple & Usefull, Great ...

Rapide, efficace et la qualité de la vidéo est au rendez-vous

Simple add-on, button out of the way and not clogging up a webpage, but still clearly visible. Deserves it's five stars here.

ça y est ça marche.

Funciona muy bien

Great: easy, simple, fast. Download button is in very good position.
Now (26.05.2021), for me, it's the best extension of its kind.
