about:config extension

Hi,

As you can see from my posts, I've just started using firefox.  I love
the small foot-print model.  During the last month or so I've been
using firefox's about:config, modifying various win2k registry
settings, and mucking around with linux.  This has got me thinking
about a possible useful firefox extension.

I use firefox on win2k and linux, and have been trying to get my
sisters to use it on the mac side.  Anyhow, it would be extremely
useful if I could use about:config to modify all my config parameters
on the three different platforms.  At it sounds rather daunting, but a
standard xml vocabulary map, might do the trick.  Has any work been done 
in this area?  If not I'd like to start a discussion.

If anyone has any thoughts on this please post your reply.

My apologies for crossposting.

Thank you and Happy Valentines.
