bit.ly preview 1.272
With the bit.ly Preview Plugin for Firefox, whenever you hover over a bit.ly URL on any web page, we display a tooltip showing the Page Title, Long URL, and any Click Data we have about the page the URL links to. If you hover over another short URL, http://tinyurl.com/5qhkwo, for example, we show the Page Title and Long URL for these links as well.

All this info should help you decide if a link is worth checking out or not.
