Firefox toolbars

[cjsmith]

My GoogleFu is insufficient. Help me, LJ-Brain-Kenobi. You're my only hope.

I've got a cute little icon in my Firefox toolbar on my work machine. It's in the navigation toolbar, if this matters. I'd like to know exactly what it does so that I can then create another, just like it, to put on my Firefox toolbar on my home machine.

All I've found so far is the obvious stuff about how to drag things to and from these toolbars. I want to edit one.

Anybody know how this is done?

No, I didn't mean that -- but that's nifty to know! :-)

I was thinking more along these lines. Here's a picture:

Imagine that right next to the Home icon (the little house), I've got another, custom one, installed by a web site. Now I want to change what that icon does.

Ah I see... well, no ideas on that one then! Let us all know if you figure something out.

So far all I have found is that a useful keyword is XUL.

There are no buttons. There is only XUL.
