This is very useful,youtube is something I am using every day and this makes downloading music from youtube in mp3 format so much easier than before.Great extension.

Firefox recommends the addon. I add it to my browser. I want to download a song ... I am automatically linked to a page and have to download another program to my PC. I think it's a virus, I'm deleting the addon.

But hey, this is Firefox and Firefox recommended the addon - it cannot be a virus. I read the FAQ on the developer side, they look honest. I download the addon again, I download the "program". I want to download a song and convert it to MP3. I am redirected to a page and have to buy a license that costs 19 euros. I am considering buying a license, but I do not get an answer as to how long the license is valid. Okay, I still want to pay. I cannot transfer money because only VISA, Mastercard, American Express are accepted.

Why don't you write this information in the addon description? Look up the term "transparency". What you are doing is a jungle of links and redirects!

Muito muito bom!!! TOP

Отличное дополнение!!!

In the past, this has been a useful and dynamic add-on. It has now been monetized (watermark/stamp on downloaded videos) and requires installation of an external application that is not the git-hub secured version. The "companion app" is basically just FFMPEG, which many have installed by official sources but this official one is not recognized by the add-on. This leads to unnecessary and risky additional apps. Sadly, there are no brave alternatives for websites besides YouTube, Vimeo, etc.

超棒！

It's paid now, what isn't clear when you install.

Great plugin!!!!

Non-functional on Firefox in 2020. Asks for Companion App, but till doesn't work after installing it.
