Duvet-dayz has an outstanding tip sheet on firebug (via dzone) with keyboard shortcuts and mouse actions arranged by Windows, Linux and Apple operating systems. Firebug remains one of the very best tools for developers in existence, in my opinion; it’s incredible to think that so much functionality is packed into a Firefox extension. Most developers I know couldn’t live without it and use it continuously throughout the day. This Firebug tip sheet can only help us all use this wonderful tool even faster.
If you use the firebug addon a lot, Digital Media Minute has done articles before on firebug tips as well a very popular post on debugging JavaScript with firebug for Firefox.
