If you want to download HD it asks you to pay for this. No way, I deleted this add-on right away.

Update: Now, four years later, I tried it again, and the extension immediately allowed me to download videos in maximum quality for free. I don't know when they'll start charging, but for now, this extension has saved me, and that's absolutely wonderful.

Shame I can't save just the audio as an mp3 in standard definition and not high but works otherwise like it says it does.
Oh, also, it doesn't work on age-restricted videos? I can watch them because I'm not on an age restricted account or anything but I there is no download button.

The addon works well, but the "One time payment" claim is false. I've been asked 3 times in 3 years to donate as he removed my access. Should be more straightforward if he wants yearly donations instead of claiming a lifetime payment.

It used to be one of my favorites but lately I am going thru avery hard time. It is not finding any links when requested a download so it fails too frequently.

You have to buy the Pro version for downloading Mp3,3GP and 1080p but I was able to download 360p with the basic add-on so it did partly meet my need.

So far so good.

Ne fonctionne pas(plus) du tout !

tried Video DownloadHelper first, which is not user friendly and needs to install extra companion. "Easy Youtube Video Downloader Express" is really easy and no extra installation! Thanks.

Useful. Not working, always send message what its needs powerful server infrastructure. And others spam. Others addons work better and not spam.
