Something is causing this badge to reload or flicker in Firefox when I use it on certain pages, such as the one that describes this problem. I'm keeping this page as a trimmed-down version. So far, I've found that when I have both #wrap div (see default.css) and style-switcher JavaScript (see below), the Flickr badge does its flicker. The first example of the badge does not have the flicker problem; I've omitted the style-switcher from that page - otherwise, the code is identical on both of these pages. I'm looking at a new style-switcher anyway, so hopefully that will fix the issue!
