Js Works In Ie, Not Ff

[mboehler3]

I have a tab-content system that I've modified from this script here.Everything works fine in IE, as it looks like this below:As you can see when you rollover a tab, a black outline highlights that tab. But in Firefox, only the first tab has the black outline on the hover. The rest of the four tabs do not rollover, and thus cannot have their hidden content shown.Is there an explanation for why this works in IE and not FF?Here is the JS:

I figured this out - for some reason, adding a "clear" underneath the main tabs <div> did it. Not sure why...
