Firefox + JW Player: Looped video does not get cached
When using JW Player to show a webm video on a HTML page in a loop, Firefox re-downloads the video again and again for each loop that gets played.
This does not happen in Firefox with a plain <video> tag, and it does not happen with Chromium and JW Player.
Open this file in Firefox, enable the Firebug's network tab, and you'll see that the webm file gets re-downloaded again and again.
In Chromium, it gets downloaded only once.
Open this file in Firefox, and the video gets downloaded only once.
So we have the problem here that people using Firefox are re-downloading the video again and again, hogging their own and our server's bandwith.
This happens with JW Player 6.3.3242 (we noticed that on 5.10, too).
