     1.7 +// Bug 776129 - If a window w calls window.open, the resultant window should be
     1.8 +// remote iff w is remote.
     1.9 +//
    1.10 +// <iframe mozbrowser> can be default-OOP or default-in-process.  But we can
    1.11 +// override this default by setting remote=true or remote=false on the iframe.
    1.12 +//
    1.13 +// This bug arises when we are default-in-process and a OOP iframe calls
    1.14 +// window.open, or when we're default-OOP and an in-process iframe calls
    1.15 +// window.open.  In either case, if the opened iframe gets the default
    1.16 +// remotness, it will not match its opener's remoteness, which is bad.
    1.17 +//
    1.18 +// Since the name of the test determines the OOP-by-default pref, the "inproc"
    1.19 +// version of this test opens an OOP frame, and the "oop" version opens an
    1.20 +// in-process frame.  Enjoy.  :)
