arbitrary websites to run in your browser, or in any browser that you
intend to access? If not, then you don't need to use wrappers.
If you do think you need to use wrappers, then there are several
varieties floating around.
The Gecko 1.7 branch has no built-in wrappers but Mozilla 1.7.x and
Firefox 1.0.x provide XPCNativeWrapper.js which allows you to wrap named
properties and methods.
The Gecko trunk has a built-in XPCNativeWrapper which operates in two
modes: a backwards-compatible mode with named properties, and a mode in
which all properties are wrapped. You use new
XPCNativeWrapper(untrustedDocument) for the latter mode.
The Gecko trunk also has a system whereby all untrusted documents can be
automatically wrapped; this is invoked by a suitable declaration in your
However, there used to be a number of properties that you couldn't set
on an XPC native wrapper, such as window.location; this was only fixed
recently (bug 296967) so you would have to use a nightly build if that
is your problem.
