Well, it seems to be working again, after a long time not working... but then, they do have an uphill battle trying to stay ahead of the 'blocks' put in their way.

I have been using Easy YouTube Video Downloader for over a year, and except for the few times that there were delays due to YouTube changing its scripting, EYVD has been superb. I use EYVD to download music to listen to before I buy the artists' CDs. EYVD has saved me hundreds of dollars by my discarding the music that was not as good as I originally thought. For me, EYVD is one of the only three add-ons that I use in Firefox. Update June 18, 2022: EYTD continues growing more important for me. Thank you Dishita for this addon!

This extension is really great. It is frequently updated to keep up with YouTube's frequent code changes. Be patient.

great

Best addon ever for real! Old school heroes here!!

Works like Magic.

This allows me and my guest (grand kids, friends, and neighbors) to watch at my cabin or when i am not on Wi-Fi. I believe its the best and will continue to support this amazing project.
