I keep seeing this question around and am wondering if anyone has had any luck? I tried an add-on, but that didn't work. All the other stuff (script, etc.) is beyond my comprehension. Will Firefox ever add this feature? Or, would someone be willing to do a step-by-step?

You can check some prefs on the about:config page and try to toggle them to see if that has effect.
