firefox issues with colorbox and jtransform

Hey all, this is my first post... But I've been here a lot.

I'm having trouble with ColorBox and jqTransform.

I'm fairly certain its a css issue....

The website I'm working on is: http://vfyfs.com

When you click login or register a box comes up and prompts the user to either login or register.

The box shows up fine in both chrome and ie8

The problem is in firefox.. the inputs are messed up and the box is too big and unproportional...

and help is greatly appreciated! thanks!
