bgiframe does not work on FireFox

bgiframe does not work on FireFox

Hi All,

I tried to create an iframe in a div, using bgiframe as below:
$("#panelrightbody").bgiframe({ top: 0, left: 0, width: 1280, height: 800 })

The iframe is created successfully in IE8, but not in FireFox (v3.6.12).

I used this script:  jquery.bgiframe.min.js

Please help me to find out the root cause.

Thanks,

Triet
