works well

OK

works with some videos but you have to be a "pro" user for most... Almost a perfect extension but no thanks.

Does not work. You must have pro version . This is a pc :-(

really good and convenient extension. A honest one.

With most downloads you are supposed to upgrade to the Pro version? Thank you no, that's what I call scam!

Apparently it does not work for MP3 files. Maybe youTube changed something. It works fine for videos, so I'll keep it. Thanks!

I have been using this add-on for over 5 years and highly recommend it. I use the pro version and the tech support is outstanding!

nice tool

it works!!

and you get also support from developer :-)

I have used this extension for years and years now. Maybe a decade already and I have no bad words to say about it.

It still is actively kept up to date and fixed when youtube breaks something. All the rescued videos to your HD work flawlessly. I have the pro version and fully recommend doing the donation for it.

Best Firefox extension out there ever created. Wholeheartedly fully recommend.

the addon works fine and the video transformation works fast and reliable. I can recommend the invest in a pro version - it's worth a donation.
