Anyone want to critique my website?

Nor are there spaces between the three lines that compose the address.  On Firefox, it looks like I was a blank line in between each of them, which I don't. 

It's because there is a paragraph tag enclosing each one (inside of the TD tag).  Take out that and the space disappears.

I have to say that, from my experience, Firefox does some stupid things, but it works a lot harder to adhere to the W3C standards.  By the way, you can check your page for standards compliance here:
