I noticed that my blog looks different on my home computer than in
other computers.  It all tends to vary, but at the moment, it looks
fine on my home computer, which uses Internet Explorer, but on another
computer that I use, which also uses IE, the right sidebar has slipped
down to the lower right.

Then I started hearing about how things can look different in Firefox,
so at home I opened my blog in Firefox.  Not only has the right
sidebar slipped to the lower right, but the header is not centered and
is on the far left.  It looks a mess.

Does anyone know what causes this and how I can fix it?  I'm wondering
if it has always been like this in Firefox and I just never knew
because I never used it.
