 Ultimate Status Bar

Productivity 
Interclue

This status bar extension reveals what links are trying to hide from you — destination, file type and size, the possible presence of Rick Astley. It embiggens shortened URLs, and when you don't want it in your way, hides discreetly out of sight. Fully themed, you can make Ultimate Status Bar suit your look. Now available in Sparkly Unicorn Flavor!
