// Bug 762939 - Test that visibility propagates down properly through
// hierarchies of <iframe mozbrowser>.
//
// In this test, we modify the parent's visibility and check that the child's
// visibility is changed as appopriate. We test modifying the child's
// visibility in a separate testcase.

// For the purposes of this test, we want there to be a process barrier
// between child{1,2} and parent. Therefore parent must be a non-remote
// <iframe mozbrowser>, until bug 761935 is resolved and we can have nested
// content processes.
