michael@0: // Bug 776129 - If a window w calls window.open, the resultant window should be
michael@0: // remote iff w is remote.
michael@0: //
michael@0: // <iframe mozbrowser> can be default-OOP or default-in-process.  But we can
michael@0: // override this default by setting remote=true or remote=false on the iframe.
michael@0: //
michael@0: // This bug arises when we are default-in-process and a OOP iframe calls
michael@0: // window.open, or when we're default-OOP and an in-process iframe calls
michael@0: // window.open.  In either case, if the opened iframe gets the default
michael@0: // remotness, it will not match its opener's remoteness, which is bad.
michael@0: //
michael@0: // Since the name of the test determines the OOP-by-default pref, the "inproc"
michael@0: // version of this test opens an OOP frame, and the "oop" version opens an
michael@0: // in-process frame.  Enjoy.  :)
