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

+ //
+ // Bug 776129 in particular manifests itself such that the popup frame loads
+ // and the tests in file_browserElement_OpenMixedProcess pass, but the
+ // content of the frame is invisible. To catch this case, we take a
