It is so easy useable app!! I am satisfied that

The most reliable and easy to use YT video downloader there is. Not too many bells and whistles. Does what it says w/o any fuss, has been around for a long time so you know it's reliable and safe, and is well worth the small donation to keep the service going.

Been using this add-on for years, it works great to deliver the 720p and 1080p Youtube vids that have broken the other downloaders. I very gladly donated $30 to help keep this system up and running, and also donated $20 previously to use on a computer I lost in Hurricane Harvey.

This is perfect for downloading YouTube videos. I donated 10 bucks to get the pro features & it seems to have been worth it. Sometimes when YouTube changes something, the button might not appear – you gotta click on the extension icon & select a link in that case. Also sometimes I get a 'already processing. please wait or come back later' or similar message when selecting MP3 conversion. As a workaround, I just download the video in MP4, open that up in Audacity, then export to MP3. Can't say if that's a bug or something else. The developer seems to stay on the ball with fixing stuff, so I trust that issues will get fixed sooner or later. Overall, this is the best YouTube video downloader I've seen yet... :D

Works just fine.

Must-have addon. Regardless of paying a small amount of money for pro-features, it gives exactly what you want it to have.
And quick responsiveness from a creator.

Great extention, easy downloads and the developer always update it as soon as YT changes something to keep us from downloading vids. It's a pleasure to donate some bucks for this.

this extension is very great

What a wonderful little add-on! ^_^

I have been using this for a few years and it's the only YouTube video downloader that I've come across that is simple to use, doesn't have the need to install any other rubbish or bloatware, is Ad-Free, delivers everything it promises and works a treat! It's extremely small & efficient and places a very handy "Download As" button underneath the video. Can be used for Free but Well worth the donation/purchase for the premium features. A lot of other addons claim to offer you similar features but never really do and are usually buggy or stop working altogether after a while.

TIP: After donating, Bookmark the Videodroid Thanks page or save the link, because if you delete all your cookies you will need to revisit the page to re-enable the addon's pro features. If you ever have any problems, or FireFox has just updated and something's not working, make sure you check all privacy & cookie-related settings and also make sure that other addons aren't interfering. If all is as it should be but it's still not working, the developer is only an email away and always happy to help :)
