One wonderful thing about Firebug:

When editing a CSS property, pressing UP and DOWN will iterate through all of the possible values of that property. For example, editing "display: none", you can quickly find out what values "display: " can take.

I really miss that in the chrome debugger :(

True, the webkit DOM inspector can only increase or decrease numerical value, it doesn't work for arbitrary values (I actually find worse that it does not autocomplete property values)
