Multi line tooltip

Hi All,

I want to show multi line tooltips. This works fine with normal firefox, but doesn't work with portable version.
The below example shows the tooltip in two lines in normal firefox browser (and chrome/IE etc). But the protable version shows it in one line.

Can someone tell me how to show multi-line tooltips in portable firefox?

Example: (replace [ and ] with )
