Okay, so my comic Help Wanted, found here: http://www.drunkduck.com/xHelp_Wanted/
is having some centering problems on FireFox.
After we put in the new navigation buttons and icons link, the pages have been off center to the right, and its really noticeable.
Though on Internet Explorer, the centering is fine.

What should I do? Is it simply because I'm on Firefox, or is it something I can fix?

There. I put this around the comic page tag:

<div align="center"></div>

That seemed to do the trick ^_^
