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
