Menubutton control with dynamic links

[Benjamin Thompson]

I am trying to create an add-on that takes the contents of a textbox
and adds that string into a URL, much the same way OpenSearch does.
I'm having a hard time finding the correct JS code to cause a
menubutton menu item to act as if it were a bookmark menu item: that
is, send the active browser tab to a new URL.

I've attempted using [b]window.open[/b] and [b]window.location[/b], or
nesting those functions within a function of my own. I've tried adding
[b]href[/b] to my menuitem tags, but so far nothing caused any
behavior at all. The menu items appear, and are clickable, but do
nothing.

I suspect it's a scope problem, but I can't find the solution
anywhere. How do I get a menubutton menu item in a toolbar to cause
behavior in an active tab? The samfind extension does this but it
appears to be made out of a binary .jar file rather than the .js
and .xul formats I'm working with.

Does anyone know what I'm missing?

Problem solved. Someone pointed out gBrowser.

This community is very helpful but I hope the documentation gets a
little more cohesion. Information seems spread across two different
sectors of the Mozilla site which do not link to each other very much.
