thank u

muy bueno

This handy plug-in just works. No hassle. No complications. I found it in a google search. Easy install and it gives you a big green button under the YouTube video that says "Download As..."

Amazing!
It's good to be able to download audio only or video with the same addon.

Excellent downloader and super fast download. Its after one donates that the speed increases.

Does exactly as described. Well worth the cost of registration.

Ease of use.
The choice of quality of downloads.
Makes it meaningful to save selected videos.

good

The download speed where I live is only 1.5 megabits a second. This makes watching videos at any decent resolution a problem when I'm the only one using the net, and impossible when other family members are using it.
Since I watch a lot of tutorial videos, being able to download them to watch offline means not having to pause, buffer, scrub back and forth, repeat.
After using the basic edition for a while, I've just picked up Pro and gave it a try with a 1080p Blender tutorial. The transcoding is excellent and it will be a great help in the future.
Highly recommended.

Update: March 10, 2019. Still loving this app. The registration is worth every penny, and the little elves that transcode the videos on the remote servers have to be fed somehow. I've introduced another family member to the app and they love it, so we'll be donating again today.

Fantastic add-on, for every high quality format in video or audio you desire!

This is the best and ONLY video downloader anyone should ever use for Youtube! I will continue to use this ALL the time and recommend it to anyone serious about downloading videos. If you are looking for a free downloader, just remember that you will get what you pay for. Don't expect developers to do all this hard work just so you can have a cushy life!

That's a good apps

GOOD

I previously had a similar tool that disappeared after a Firefox or YouTube update, so I was thrilled to find this add-on, and to find that it works well for video and audio downloading. Also, the developer is quite helpful regarding questions or issues. Thanks!

I used this for some time until the last YouTube upgrade which stopped it (and, I believe all downloaders) from working. I rejoiced when a new working edition was announced since I'd suffered a bug that required me to visit the Activation site every time I restarted Youtube. Alas, the bug remained. I contacted Dishita and after several investigative emails, he suggested creating a new Firefox Profile. Yo-hoo! This worked.

Many thanks, Dishita for the best downloader available for Firefox. And thank you for prompt and efficient assistance with my problem.

Easy YouTube Downloader Express is a wonderful and user-friendly application. It downloads MP3 files (my particular requirement) in seconds with one-click. If you don't use it, get it.
