Looks like it's not an "addTab" method issue. I've used "gBrowser.loadOneTab" and "openUILinkIn" methods with the same result.

tabContainer listener receive the "TabOpen" event with the URL that should be opened, but no visible tab exists. "TabMove" and "TabClose" listeners didn't get any events.

In case if all three method are opened on start listener receives three "TabOpen" events, one "TabMove" and two "TabClosed" events, despite there is no new tab opened (moved, closed manually).
