[Plugin: WP Coda Slider] alignment not working in FF, beautiful elsewhere

I’m using the what looks to be awesome plug-in WP Coda Slider, a category-based post slider using jQuery.

The problem was with the original code I couldn’t get the labels to wrap to multiple lines – they just went on and on horizontally, off the page, and stayed on one line.

I fixed the problem by changing ONE element in the JavaScript code, NavContainerWidth (below). Now the slide shows up as I like in Internet Explorer and Chrome, but the alignment is all messed up in Firefox… both 3.6 and 4.0 – http://www.techwadi.org/sponsorship

Any idea why? Any other plugin I could use?

Original:

navContainerWidth = slider.width() + slider.siblings('.coda-nav-left').width() + slider.siblings('.coda-nav-right').width();
ul.parent().css({ width: navContainerWidth });
switch (settings.dynamicTabsAlign) {
case "center":
ul.css({ width: ($("li", ul).width() + 2) * panelCount });
break;
case "right":
ul.css({ float: 'right' });
break;
};

New, multi-line:

navContainerWidth = slider.width() + slider.siblings('.coda-nav-left').width() + slider.siblings('.coda-nav-right').width();
			ul.parent().css({ width: "580px" });
			switch (settings.dynamicTabsAlign) {
				case "center":
					ul.css({ width: "580px" });
					break;
				case "right":
					ul.css({ float: 'right' });
					break;
			};
