Sticky 2nd Nav Menu

Hello - I love the way the #masthead is sticky and stays at the top when scrolling down. Is there any way to do this with the #secondary-menu? I have tried some plugins - Sticky Menu and MyStickyMenu but they both have problems with Chrome vs FireFox and different size browswers which #masthead doesn't have. It looks like #secondary-menu is inside the #main-wrapper. Do I have to move it into the masthead or create a new widget? Here's the site: chezjillchocolates.com
