Here's an odd one,
I'm working on a site www.tereshalee.com AHP ver 3.3.2
I have a text widget in the left sidebar that has a couple of links in it, one to twitter and one to MySpace. The MySpace link/image shows up fine in IE and Chrome, but is oddly missing in Firefox. Looking at the source, it looks like it's there...
Have tried relinking, flushing the WP Cache as well as the FF cache.
