If you’re using the same code from the demo, then there’s some code that looks like this – autoplay=1 ….if you change that to autoplay=0 then it will turn off the autoplay.
The video works in all browsers except in Firefox for some reason. When firefox loads the site it plays the video automatically. If that’s what is happening on your end, then changing that part of the code above should fix it.
The video in Firefox only plays on the homepage though, it doesn’t start on other pages. I’m guessing maybe you added the video in your Primary sidebar? If the video is inside the homepage widgets, then it’s not supposed to show or be active on any other page.
If you have a link let me take a look at it so I can be sure.
