Showing up differently in Firefox

Can anyone help?

??

Anything guys? My site is growing in hits by the day, and this is becoming a problem.

Start with the validation errors..
Click me.

I’m a little unclear-do I need to essentially delete all of the errors it’s listed? Most of them seem to be related to the quotes bar I have at the top of the page, which I don’t really want to get rid of/wouldn’t know how else to embed it.
