Answer 1

The general consensus is that styling radio buttons in Firefox with CSS is a fool's errand. But there are several workarounds that achieve the same effect. My personal favorite is to hide the actual radio button and instead use images to show if it is checked or unchecked.
There's a nice working example here:
Mozilla Firefox input radio button styling and default settings

Answer 2

Styling input elements (in particular radio buttons and checkboxes) can be unreliable across navigators. You're better off applying the styling to the label or a pseudo element.
