Can I view the HTML source of an email sent to an Gmail address from an Android device? I have a Samsung tablet and would like to check the HTML source code from a Gmail message. Does anybody know how to do this?
I'm using Firefox Aurora for Android; I can simply type view-source: in front of the address in the address bar, and a new page loads with the HTML code, etc...displayed in a formatted viewer.  I'm not sure if the other browsers have the same functionality, or what the corresponding command for those would be. You can find Firefox Aurora for Android at their website.

There's also a convenient Add-on that creates a menu shortcut for this function.
