Using the TITLE attribute (on an anchor) to provide a multiline tooltip

The TITLE attribute produces a popup tooltip on all modern browsers. In IE6 you can produce a multiline tooltip by injecting a CR, but is this limited to IE? What about Firefox?

Inspired by WebmasterWorld HTML Forum:

 in the tooltip seems to be better than actually hitting the ENTER key in the source. But it only works in IE.

This tooltip should have 2 lines

Is there a limit as to the length of the TITLE attribute (ie. Tooltip)...?
