[jQuery] Trying to write a MacFF2 Transparency Fix - Need help with .version

Here is my code:

        // Mac FireFox 2 Transparent Background Fix
    if ($.browser.mozilla && (browser.version < 3.0)) {
        $(function(){
            alert('This is FireFox 2!');
            $('body').css('background', 'red');
        });
    }

I think that .version is blowing up the script. Can someone help me
with what I am doing? Lemme know what I missed.

Thanks.

Dave
