Bug 31607: App menu items stop working on macOS
Avoid re-creating the hidden window, since this causes the nsMenuBarX object that is associated with the app menu to be freed (which in turn causes all of the app menu items to stop working).
More detail: There should only be one hidden window. XREMain::XRE_mainRun() contains an explicit call to create the hidden window and that is the normal path by which it is created. However, when Tor Launcher's wizard/progress window is opened during startup, a hidden window is created earlier as a side effect of calls to nsAppShellService::GetHiddenWindow(). Then, when XREMain::XRE_mainRun() creates its hidden window, the original one is freed which also causes the app menu's nsMenuBarX object which is associated with that window to be destroyed. When that happens, the menuGroupOwner property within each Cocoa menu items's MenuItemInfo object is cleared. This breaks the link that is necessary for NativeMenuItemTarget's menuItemHit method to dispatch a menu item event. --- xpfe/appshell/nsAppShellService.cpp | 4 ++++ 1 file changed, 4 insertions(+)
