About this extension is the exact opposite of what is says which is that it works. All i got was an excuse stating Google changed the formats [all] and only PRO users could get 1080p.

This is the best you tube downloader and is so simple to use. It puts a download button on all the videos and when you tube change their code it is updated very quickly for a one man band

it's so incredible and helpfull also time saver add-on i like it much

One of the most useful add-on

Doesn't work. Period.

easy, fast and simple. Just excellent.

Click bait offering a pro paid version that works.

worked easily and with very little effort on my part.

Parfait

The downloader I was using borked.
I've just started using Youtube Video Downloader this evening. 720p and mp3 downloads working. No probs.I have not tried 1080p. If it looks good full screen on Youtube 720p seems fine. I'll try 1080p if something looks exceptional and see if it makes a diff.
I'm running Firefox on Linix.

Best YouTube Video Downloader available. I have been using it for years and recommending it to everyone the entire time. I highly recommend it.

Can't get it to work

This add-on seems to have 5000 fake reviews. How could Mozilla recommend this add-on ?

Anyway, I installed it, tried to download a 1080p video and got a message that I have to pay for a pro version? Are they serious ??? Add-ons are supposed to be FREE!

What a waste of time.

ACCESS ALL DATA FOR EVERY WEB SITE I VISIT ???? WHAT ?? ?? IT SHOULD ONLY ACCESS YOUTUBE! PROBABLY A PHISHING ADDON.
