How to open XUL window/dialog in a new tab?

Is it possible开发者_Go百科 to open .xul file containing window or dialog as a new tab? I can open it as a separate window using window.open or window.openDialog, but I would prefer if it were a tab.

You can use loadOneTab():

gBrowser.loadOneTab("chrome://.../window.xul");
