I often browse news aggregators like Reddit and I want to be able to have one Firefox window open on each of my two screens, and when I middle click on a link on my left screen, it will open up the tab on my right (2nd) Firefox window (and each successive middle click that opens links on my left window will also append consecutive tabs on the second window).
I know that there are some plugins that can open up new windows, but if I do that I'll have to many windows open and I'd rather manage my open news stories via tab bars rather than with windows (clearer, more efficient to browse, and easier to bookmark).
Is there a Firefox addon with which I can middle click on a link and it will open it in a new tab in my other window?
