how to change nautilus' default browser?

[Mike Wright]

Hi all,

Subject says it all.

I've gone through every option I could find, right clicked everything, 
grepped through .nautilus and .gnome2* and haven't the slighted idea why 
nautilus insists on opening Chrome when the system default is set to 
Firefox.

(IMO Chrome isn't ready for prime time: the Firebug extension for it is 
a joke, its UI is tedious; it may be faster at some things but its 
shortcomings *way* overwhelm any of its benefits.)

Any takers?

TIA,
Mike Wright
