No playable sources found in Firefox on Windows

When I try to view my livestream I'm getting the error "No playable sources found" when I use Firefox on Windows. The player works correctly in IE and Chrome on Windows, and Safari, Chrome and Firefox on Mac. Even mobile devices are working, Firefox on Windows seems to be the only one who doesn't want to play along...
The Windows PC's I've seen this error on all have the latest version of Flash Player installed and run Windows 7 Professional 64-bit. We are using JWPlayer version 6.11.4923, the latest update at this point, if I'm not mistaking.

Anyone who can point me in the right direction? If you need any more specifics, please let me know!

Do you have Flash installed for Firefox? You are running an RTMP stream here for the desktop, so Flash is required.

Yup, works fine for me with FF35 on Win7. I'll wager you just don't have Flash installed on FF (it has to be installed separately for IE and FF).

Launch FF and visit this page:

Well what do you know... Something so simple!
Turns out there was no Shockwave Flash add-on in the Firefox list on my test clients. Re-installing the Flash player fixed that and as a result the player works properly again.
