title: Freeze a JavaScript?
body: <p>I'm making a custom CSS theme for Facebook and I'm trying to view the CSS code for the little pop-up that happens when you hover your cursor over someones profile picture. I'm using Firebug to view the CSS code. It's viewable, but I cannot view the CSS code fully, because once I take my cursor off the profile picture, the pop-up disappears, then Firebug doesn't display the CSS code used for it. So is there a way to freeze open the JS so when I take my cursor off it doesn't go away? Or is there anyway to freeze the pop-up open?</p>
