This allows you to download all true qualities available - wonderful.

I seems to be yt-dlp integrated into FF and a simple, clean app. (No need to use the console/FFMPEG finicky combo.) I highly recommend getting the free app. I was hesitant at first, but there are no catches. Good set of options, and you don't even need to go to the actual video, you can copy a URL and the app automatically reads it. You can even que up multiple videos!

It can put a heavy load on disk bandwidth and processor, depending on the size and format you choose. Just be aware of that.

My only minor nitpick is that it doesn't have more file save location options, like setting a default, or use last folder. Oh, and the infinity sign that comes up over the download % worried me - i thought it was stuck, but it wasn't.
--- I'm so thankful i found this. Thanks unidl!

I can't live without this addon, love it, been using it for two years now. Amazing work.

the best I could find. thanks for free functionality

perfect

Excelente. Muy útil.

Works good. Needs to be more popular.

simply the best, fastest down loader I have ever found. If you're not using this you should be!

Incredible add-on and perhaps the only one that works on Firefox mobile. You have to switch to desktop mode though. Fine with me
