Comment 54 for bug 19250

"You shouldn't rely on tooltips to convey so much information. If it's not
obvious from your form what something does, the form should have the help text
directly on it."

It was just an example. I use tooltips on my personal webpage in a table if
recent visitors. It's just a small table so I cut off the text of the IP
address/hostname if it's too long. Hover the mouse over it and the full name
gets displayed along with the referrer (referrer on a separate line). Displaying
the information every time would hog up way too space, and clicking on a link to
go somewhere else to display those two lines would be overkill. The tooltip
however, works great for this.

I'm just saying that tooltips should have multiple lines. If the title tag won't
support it then there should be an alternate way of doing it. Unless you can
think of a reason tooltips ought not be able to have multiple lines?
