Browsers need a "never open a new window" user option. Open a new tab instead. - When you open a new window, there's a good chance that I'm going to accidentally click again on the parent window. The popup loses focus, slips behind the parent window in the z-order, and I have to pick it out of the taskbar or Expose. It would be a much better experience to pop the new window in as a new tab. When you hit 'submit' or whatever the tab closes and your original tab is back on top. This could be entirely a user-defined option too, in Chrome all tabs/windows are interchangeable by dragging.
