Status: RESOLVED DUPLICATE of bug 300079

(Core :: JavaScript Engine, defect)

Description

The is similar to bug 344052 but happens only in chrome.  When this script is run in a XUL page:

Function.prototype.foo = function() { alert("foo"); };
var f = function() { };
f.foo();

...the last statement will raise the error "f.foo is not a function".  Note that:

var f = new Function();
f.foo();

..does work.  Also note that all of this works fine in a web page as well as in xpcshell.


Reproducible: Always

Gah, I meant to say that is similar to bug 343966, not bug 344052.

I'll update the summary of bug 300079 to make it more obviously the dup target.
