Weird problem with Firefox 3.05 on Windows

I created a simple Visual JSF Project with several pages.
The problem is every time I go to new page it shows only blank page.
I have to refresh page every time I change page.
This kind of problem happen only on Windows (I test on XP)
but working fine on Linux (Ubuntu).
The browser I use on both OS is Firefox 3.05.

IE 6 is working fine on XP.

Any suggestion?

Thank in Advance
