Firefox 3 Beta 4 on Mac OS X, first impression

Secondly, Firefox 3 Beta 4 in OS X does some strange rendering. It doesn't render one of my clients' website correctly in OS X but it looks normal in Windows. If you take a look at the screenshot below, the Contact Us text is rendered just below the cyan box. This doesn't happen on Firefox 2.0.0.x in OS X.

It uses OS X form controls - which is a bit disadvantage for me because everytime I want to check what it looks like on Windows I'll have to go back to Windows again.
