Probably the easiest way to do this is by injecting part of the script
into the page. That way, the script you inject runs as though it was
included in the page, and has full access to all the page's variables,
functions, etc, but has no direct access to various privileged
Greasemonkey APIs. To do this, append a <script> element to the page
with contents set to whatever you're injecting; it's easiest to inject
whole functions, because you can simply do something like the following:
function example(param1, param2) {
// Do something with its parameters
return param1.toString() + param2.toString();
}
var elemScript = document.body.appendChild(document.createElement("script"));
elemScript.innerHTML = example + "\n\n window.alert(example(1,2)); // Call
example from in-page code";
and the function's source will be included in that <script> element
without much work.
By the way, when Anthony says something is unsafe, he unfortunately
means it. unsafeWindow can be *very* unsafe, because it allows the most
seemingly innocent of script operations to be perverted by a malicious
web page and do all kinds of nasty things with e.g. Firefox internals --
for example, making unrestricted cross-domain requests (to your bank,
perhaps?); performing denial-of-service attacks with GM_setValue; and
all kinds of other things.
Don't use it.
