Since bug 47903 landed, the output window is empty and there are NS_ERROR_DOM_WRONG_DOCUMENT_ERR errors in the console. This is because the code relied on Mozilla's (sane IMHO) lack of caring about the creating document. Fix is to call adoptNode gratuitously.
Created attachment 246496 [details] [diff] [review] adoptNode with fallback action This is much like ChatZilla's patch, in bug 361657. The command-manager change is to fix installing command keys on new windows, which is necessary to make the floating views work. The rest should be pretty clear - the change in ss_syncframe is equivalent to the output-window.js change in ChatZilla.
