In Mac Firefox, when an element is anything other than opacity:1, the text is rendered 'thinner' or lighter in weight. This means that, for example, when you fadeUp, text is 'light' in weight until opacity:1 is reached. The transition from opacity:.999 to opacity:1 is very noticeable as all the text in the window jumps from being thinner to full weight. Fading only to .999 means that all the type remains thin, but can be preferable to the more obvious 'jump' effect.
