[Greasemonkey] javascript scope between browsers

[Aaron Boodman]

So you want to open a window from a greasemonkey script, then from
that window call functions defined in the greasemonkey script.

Um... So greasemonkey runs in a separate scope from either window. So
you could basically do the reverse of unsafeWindow with something like
this:

unsafeWindow.gmScope = this;

|this| points to the global scope unless you happen to be running as a
method of an object at the time.

It's a really ugly solution though. What are you really trying to do?
Usually what you want to do is hook events in the content document,
then do work in Greasemonkey land, then change the content as a
result.
