Been using it for years. Works like a charm.

very nice add on

The creator of this extension is a very hard-working and dedicated person; he's kept it up for a long time despite YouTube constantly seeking ways of disabling it. Easy to use and generally reliable, though sometimes YouTube does catch up--briefly, never for long. I use it in conjunction with a standalone app that does some of what this doesn't, but the reverse is also true. Highly recommended.

Perfetto downloader, veloce e facile con buona scelta in quali formati

ok

Does exactly what you need with no bullshit! AWESOME! THANKS! <3

Rápido e simples!

Very good!

very good extension

Awesome...Brilliant

I was affected by one of the windows updates... my downloader would not work for about 1 year... I decided to to re install the down loader and go pro... so I donated a very expensive cup of coffee... 30$ in US funds that's like 10,000,000 Canadian any way even after donating... I did not receive a receipt... So I emailed and emailed still not too helpful the suggestions that came back were tried but all i was able to see was MP4 down loads all across the page... finally Nov. 16 2025 for what ever reason - I went back to the down loader in YouTube and there it was MP3 in two qualities... 128 and 256 Wow.. AND IT WAS WORKING.. so I finally was a happy person... I emailed back and thanked them but, I wish that they were a little more personable... thanks anyways... Joe

In short, easy to add to FireFox, VERY easy to use. Multiple resolutions to choose from. Love it.

Tried today, Nov 18, 2025, and it's not working :(
