I had so much fun assembling the Windows XP Keyboard Shortcuts, and they proved to be so popular, that I put together another one just for Firefox. In addition to the shortcuts, I included additional reference information for configuring Firefox.
Download the Firefox Keyboard Shortcuts tri-fold. Just as with the latest version of the Windows XP Keyboard Shortcuts, do not forget to print double-sided on a single sheet of paper. Also be sure to validate the driver is set to print in landscape.
