First of all thanks for your reply/help.

Now, here is a single line as example;

aWindow.Window.prototype.__mozilla__open = aWindow.Window.prototype.open;

which I changed into:

aWindow.Window.prototype.__mozilla__open = 
Components.lookupMethod(aWindow, 'open');

to make it work in Mozilla 1.7.[7/8] but now I wonder if I should use:

Components.lookupMethod(untrustedObject, propName).call(untrustedObject, 

for 'aWindow.Window.prototype.__mozilla__open' and if so, how?
