The tool on the cover of Firefox Hacks is a flashlight. The flashlight is a portable illumination device that is typically fashioned from a miniature electric lightbulb and a parabolic reflector, which are mounted in a cylindrical casing containing an electric circuit, batteries, and a power switch. Invented in the late nineteenth century, the flashlight received its name because the batteries originally used to power the device had so little juice in them that people commonly switched the object on for just a brief instant at a time, emitting a quick "flash" of light to brighten their surroundings.

Sanders Kleinfeld was the production editor and copyeditor for Firefox Hacks. Jamie Peppard was the proofreader. Philip Dangler and Claire Cloutier provided quality control. Reg Aubry wrote the index.
