My site, www.mymethane.com, works fine in IE. In Firefox, EZ Pages and defined pages show blank white space where the content should appear.

What's weird is that the blank space is exactly the right size for the missing content. Looking at the source code with FireFox, the content appears to be there. And it's not like the content is white-on-white--I can't select it with the cursor, so it appears to be truly missing. Except that it's not missing, because it's occupying the appropriate amount of space.

I'm guessing that some small html glitch is making Firefox treat the content as something other than what it is.

I'd be grateful for any help.
