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

Used to be good when it worked, free 720p downloads and mp3, now they want money for everything.

Doesn't actually do anything. Can't download videos, can't download audio. Video DownloadHelper is better in every possible way and actually works.

Works a treat for me - THANK YOU

Works great and is always updated to keep working even with the big changes that youtube keeps making every year.

A Favorite Add-On For Me! The Thing I Especially Like About This Extension Is That It's Useable On My Cellphone. I Have The Mobile Firefox & The Extension Download As An Add-On To It. It's EASY & GREAT! 🙂

Does not allow 1080 downloads without Pro version.

estupenda extension

Very clear, easy-to-use add-on. On my very first download I ran into the upgrade wall but that was explained properly and worked well. Unfortunately, I misunderstood originally and ended up getting a Premium YouTube trial, that I didn't really need. If I end up using this frequently, I will certainly make further donations.
Have now been using for over two years and the extension continues to work well. Highly recommended.

Videos can not be saved in their nativ Resolution, if the Resolution ist different from 144, 360, 720 or 1080. For example: 480p-Videos can only be saved in 360p format.
Videos lassen sich nicht in ihrer nativen Auflösung speichern, wenn diese nicht 144, 360, 720 oder 1080 ist. Bspw. lassen sich 480p-Videos nur im Format 360p speichern.

Absolutely the best one button download for youtube.
