I wish all external links on perlmonks had target="_blank". That would save me from needing to control click on external links.
I'm glad they don't. I haven't made the switch from Mozilla to FireFox because in Mozilla (and Netscape), the difference between opening a link in the same window or in a new window is a slight adjustment of my index finger: Button-1 vs Button-3 (left button vs. middle button). In FireFox, Button-3 opens a new tab. I prefer windows over tabs, as I run a well tuned window manager, and not a tab manager.
