| 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. :) | |
