Or so it would seem. I absolutely hate new windows. I use tabbed browsing aggresively. When Firefox 0.9 came out, the Mozillans had changed the standard behaviour from allowing me to control what tab new URL's were accessed from, to automatically opening a new window. Fortunately the Single Window plugin fixed that (almost). Now they've changed the behaviour again and broken the Single Window plugin. I really, really hate that - to the point of switching browsers.
