Unfortunately I don&#x27;t think so.  In fact you can&#x27;t even specify that you want it to <i>be</i> a tab, as opposed to a new window, but the default in all major browsers is a tab these days.<p>I haven&#x27;t tested, but you might be able to kind of fake it by having the tab immediately before the one you want to open do the opening.  That wouldn&#x27;t work for tabs that have opened external sites (the stories themselves), but you could at least send a message to one of the other HN tabs telling it to open your new tab, which should give you some control.
