New Version of Blogger

I have just migrated the whole Blog over to the new version of Blogger and the right navigation bar is no-longer pushed down the bottom of the page when viewed in FireFox. However all my post titles are underlined and I cannot find where that is specified. Otherwise I am happy with the changes. Like I can now publish posts instantly, make template changes instantly (that used to take a good two minuets), editing the Blog template is now easier and I can add post category labels.
