Is it possible to view HTML source auto-formatted in Firefox

Is it possible to view HTML source auto-formatted in Firefox I am writing a Web site in PHP, and the HTML it renders is not well formatted and hard to read in Firefox (most of it is on a single line).

"I normally use Firebug for debugging html output.

This allows me to se the html as it's rendered by the browser, together with the well-formatted source in Firebug. I can also inspect elements in the displayed html and see where they come from in the originating html source."
