[Greasemonkey] javascript scope between browsers

[James Cowan]

Hi

I am puzzled by javascript scope within greasemonkey/firefox extensions.

In normal web app, I can open a window (wdw = window.open(...) and then 
within the parent call the child using wdw.someFunction() or within the 
child execute a function in the parent using window.opener.someFunction.

Within a greasemonkey script or firefox extension, I want to open a window 
and then make calls from parent and child to functions within the extension. 
The standard web technique does not work - I guess because the functions are 
not in the scope of the window but of the browser.

Is there any way around this?
