I've been using Firefox this past week after being an exclusive safari user for awhile.

It's great, but when I do the mouse-over thing to preview threads on UG, it shows it as a long line across the screen instead of a nice paragraph shaped box.

How does I fix it?
You don't. Small sacrifice to make for such a good piece of software.
Ticking away the moments that make up a dull day
You fritter and waste the hours in an offhand way
Kicking around on a piece of ground in your home town
Waiting for someone or something to show you the way
