Everyone has their own favourite Firefox extensions — that’s how the browser is designed. I just discovered a small one via idle browsing: Popup ALT Attribute. It was designed to show alt attributes in tooltip-style, but also enables multiline tooltips, usually from the title attribute. You can try it out by mousing over the two links above: the link titles aren’t truncated any longer.
For the record, my lonely-island Firefox extensions are Scrapbook, Tab Mix Plus, Spellbound, and the Web Developer toolbar.
