Google Chrome Extension Hello World
===

I am going through the "Hello World" example on the Chrome dev pages (http://code.google.com/chrome/extensions/getstarted.html).

One thing I would like to do is to be able to grab the current selected tabs location.href and document.title.

For example if I am on www.apple.com and click the popup toolbar button I'm not sure how to access the www.apple.com document.
