Well I had to add this.. Happy Solstice Eve.
[Seems my videos are not playing using the latest Firefox browser..that is a first..must fix..they do work on Chrome.
A note on how I fixed this: “Try turning off hardware acceleration for Flash, that can sometimes resolve issues with Flash videos not playing. Right-click on any Flash video, click “Settings”, select the Display tab and uncheck “Enable hardware acceleration” … now they play again!]
