The best online YouTube video downloader. I have used this add-on at least ten years. You can download 1080p videos or convert videos to mp3 high bitrate files. If there is a technical problem, one gets a good e-mail support. I always get a reply if there is a problem with the add-on.

Lame. Doesn't actually let you download MP3s unless you pay for "pro". Not worth!

Es genial puedo descargar el video que quiera y en cualquier formato, buen trabajo.

I remember when this ACTUALLY WORKED FOR FREE, NOW WE HAVE TO PAY FOR THIS "PRO" TRASH AND I DON'T SEE AN ICON ANYWAY SO THIS IS A GREEDY HUNK OF TRASH!!!!!!. Why this is greedy is because this appears as fully free unless you scroll ALL THE WAY DOWN to the place where it says "use pro for, this is now me speaking for a bit, EVERY MAJOR FEATURE, LIKE MP3 DOWNLOADING AND 1080P DOWNLOADING". Never using this again, using no downloader unless there comes further notice.

This is a GREAT add-on. I'm an old Co-Lo Data Center tech & I almost never ever buy Xtra little software. But this YouTube DownLoader is absolutely one of the most useful and Xcellent working add-ons you could have for FireFox. I use it several times a day almost every day / all day Long.

Working to slow

Requires you to pay before it will let you download anything. You get a "Download" button on Youtube but this "download button" actually forwards you to a page that requires you to pay at least $10 to use the extension.

yt-dlp is free people. Use that.

If there is an emoji(Segoe UI Emoji) in the page title, it cannot be saved. ex) https://youtu.be/PvA2oozgpxo

greedy trash

It does 99% of things I wanted it to do. Support is excellent, I normally get an answer within an hour of asking for help. Highly recommended.

Thank you.

requires you to pay if you want to download anything higher than 720p
