Dear,

I am trying to download & convert a video on Youtube through Firefox Add-ons on Mac OS X 10.9.4. When I download there is a message: " [ JavaScript Application ] Conversion requires an external application that appears to be missing on your system. Configure conversion ? ".

I downloaded Java and JDK for Mac but the same message still appears when I download or download & convert a video from Youtube.

Kindly would you please help me in this issue ?

Thanks and regards, Omar Bassiouny

Hello, Can you tell us which addon you use?

Go to the Mozilla Add-ons Web Page {web link} (There’s a lot of good stuff here) and search for what you want.

You could also download the video as is, and use a free converter program to get what you want.

I've downloaded Wondershare but while downloading it stops and there's a message says that Failed obtaining video info !!!

Download has worked but the problem that the video itself was in low quility and I was downloading in HQ. Then, I used Wondershare to convert it to MP3.

Thank you very much for your cooperation :)
