How do I change the font size?

[Lee Schierer]

I was viewing SMC on my new laptop when suddenly the screen refreshed and the font size on SMC was quite a bit larger. How do I get back to the smaller font size? Other websites appear at normal size, only SMC is large type. I don't know what I did to make it larger. I'm using Firefox 8.0.1 on a windows 7 machine.
