4 // Bug 776129 - If a window w calls window.open, the resultant window should be
5 // remote iff w is remote.
6 //
7 // <iframe mozbrowser> can be default-OOP or default-in-process. But we can
8 // override this default by setting remote=true or remote=false on the iframe.
9 //
10 // This bug arises when we are default-in-process and a OOP iframe calls
11 // window.open, or when we're default-OOP and an in-process iframe calls
12 // window.open. In either case, if the opened iframe gets the default
13 // remotness, it will not match its opener's remoteness, which is bad.
14 //
15 // Since the name of the test determines the OOP-by-default pref, the "inproc"
16 // version of this test opens an OOP frame, and the "oop" version opens an
17 // in-process frame. Enjoy. :)

27 // default, we're going to open an in-process frame.

32 iframe.setAttribute('remote', remote);
34 // The page we load does window.open, then checks some things and reports
35 // back using alert(). Finally, it calls alert('finish').
36 //
37 // Bug 776129 in particular manifests itself such that the popup frame loads
38 // and the tests in file_browserElement_OpenMixedProcess pass, but the
39 // content of the frame is invisible. To catch this case, we take a
40 // screenshot after we load the content into the popup, and ensure that it's
41 // not blank.
