View Source in Tab Bookmarklet
Holy cow, look what I just made! Drag this bookmarket to your toolbar and use it in Firefox to toggle between the view-source: pseudo-protocol and the rendered webpage.
Now if only I could associate a keyboard shortcut (thinking Ctrl+U) with this function, I’d be golden.

Here, have VSIT (http://www.joshisanerd.com/vsit/), an extension that does much the same thing. But with a keyboard shortcut: Ctrl-Shift-U, since I couldn’t figure out how to kill the Ctrl-u event from hitting the view-source functionality of mozilla/firefox (grumble).
