Hello, we are working on a wordpress theme and we found a little issue. When we try to access a webpage from a iMac using Mozilla Firefox, the video from our slider doesn't work. And we don't have any clue how to make it compatible with this browser.

p.s. on other browser we didn't had any issues with this.

Thank you!

Kind Regards, Dumitru.

Firefox does not come with an MPEG decoder built-in (for patent-related reasons, I think), but instead will use features provided by the operating system, where available. Unfortunately, MacOS X is lagging Windows and Linux in this area. You may need to code the slider to use a plugin (Flash, QuickTime, etc.) as a fallback method of playback.
