UPDATE: Pandora has been redesigned and no longer offers an explicit mini player, so this bookmarklet no longer works as intended.
Without further ado, I give you the Pandora Mini-Player Bookmarklet. Tested in Firefox 22.214.171.124, Mac OS X 10.4.7.
To use in Firefox:
- Drag the button below up to your Bookmarks Bar at the top of your Firefox window, below the Address Bar.
- Click the new bookmark to enjoy the Pandora Mini-Player at any time!
