Steps to reproduce:
1. open: http://www.iuvideo.com/2012_iuSite/
2. the flash video (Vimeo) plays automatically
3. pause it
4. open one of the featured videos
5. the rlightbox opens
6. the first video starts playing again

I’m the author of the lightbox. One dude reported this issue in github bug tracker. He says that there is no such a problem with other browsers. Only with Firefox.
As I*know the code, I don’t think it is my fault. But I‘m not sure for 100 per cent.

Could you tell me if it is Firefox issue or not? Or maybe user’s, or mine?*

Thanks in advance!
