| michael@0 | 4 | // Bug 776129 - If a window w calls window.open, the resultant window should be |
| michael@0 | 5 | // remote iff w is remote. |
| michael@0 | 6 | // |
| michael@0 | 7 | // <iframe mozbrowser> can be default-OOP or default-in-process. But we can |
| michael@0 | 8 | // override this default by setting remote=true or remote=false on the iframe. |
| michael@0 | 9 | // |
| michael@0 | 10 | // This bug arises when we are default-in-process and a OOP iframe calls |
| michael@0 | 11 | // window.open, or when we're default-OOP and an in-process iframe calls |
| michael@0 | 12 | // window.open. In either case, if the opened iframe gets the default |
| michael@0 | 13 | // remotness, it will not match its opener's remoteness, which is bad. |
| michael@0 | 14 | // |
| michael@0 | 15 | // Since the name of the test determines the OOP-by-default pref, the "inproc" |
| michael@0 | 16 | // version of this test opens an OOP frame, and the "oop" version opens an |
| michael@0 | 17 | // in-process frame. Enjoy. :) |
