This one works, I have been using it for a long time. I really haven't had any issue with the firefox/EYVDE combo.

perfect

Functional, easy to use, and rarely crashes. One of the best ones out there!

Love this add-on. Developer works very hard to overcome changes that youtube keeps coming up with to stop downloading capability. I am very satisfied with the developers hard work!
Download and buy developer a coffee :)

For a One Man show, This is an excellent tool.

I have been using this YT Video Downloader for a while now and find it to be indispensable. It works almost flawlessly and is much easier to use than the others that are out there. I highly recommend it.

Really Works!

I am finally able to assemble instructional videos in one folder. Simple, easy, and very effective best describe this little wonder.

So simple to use and yet so efficient !!! Thank you so much !!!

Gets better and better - constantly supported by devs. Updated nearly as quick as YouTube make changes trying to prevent downloads. Better than anything else i've tried. Keep it up pls!

These guys are simply brilliant & are always working to make it even better. Definitely give it a go!

Legacy Firefox 52 finally fell through on 24 July, but moving to the Quantum ESR fixed it. I've had nothing but good results from this plugin since then.

Terrific downloader that I've used for years. The best and with the best support and updates. How could I complain?

Great Add-On, works very well, use it for quite a long time and still satisfied.
