The maker tries to update as soon as possible is my impression. Every two months or so, the app's not working good. An update now and then fixes this. Very fast, easy to use. You might keep it a secret like a lot do.

Was using another downloader which unaccountably started creating files unreadable by WMP, VLC, you name it...
Installed this and it worked first time with no fiddling around digging for codecs etc; very impressed so far!

2024 update: I should have left an update before now. This is still THE best video downloading addon around. Very easy to use. Please support the creator of this by donating and leaving a review. I cannot praise it enough. There are a lot of junk addons you will waste your time and maybe even money on, but believe me, this is the real deal. I have been using it for several years and highly recommend it. It gives you multiple formats you can download in, and works each and every time. Use this one before others and you will not be disappointed. You do have to donate for pro features, however I have no problem supporting developers whose apps do what they are supposed to do. Creative talent deserves support.

very good ,add on perfect for downloading from you tube .

program is great
support is "friendly"

Fonctionne très bien. Le téléchargement des vidéos est facile et rapide.
Works very well. Downloading videos is easy and fast.

good

IT'S A SCAM
I've payed a PRO user the last year and didn't works right now and they told me that i should pay again! because they have a new license activation system. I'm very angry

I've used other youtube downloader extensions and this one does seem to earn its #1 rating. This one is self-contained (no other extensions or converter programs necessary) and works as advertised with some nitpicks. The download button does not show up when viewing videos in a playlist. It would also be nice to have an alternative to the download button in the menu bar (in case youtube does another sneaky interface update). The extension's built-in description in the add-on manager is a little messy and could be made to look more professional (as appropriate for such a useful extension). Although there are other downloaders that can work with sites other than youtube, I don't mind this one working well with just youtube.

I was told about this by a dear friend in California and it seems great

A reminder, this add-on isn't free, a lot of its feature, for example: hq video and mp3 is disabled if you're not donating. So consider that before installing.

wouldn't work, no button to download

ok thanks

Amazing

It's not free at all ;) It working only pro (paid) users.

Se ha convertido en uno de mis favoritos y la vengo usando desde hace tiempo, pero es una lástima que la opción mp3 no sea gratuita

Very easy to use, and it works flawlessly..!
