Comment 121 for bug 395749

It's not distracting for something to happen when you click a link; it's distracting for *nothing* to happen when you click a click.

Sitting around for a while after clicking just to realize that the browser missed the click is aggravating, not "zen". The tab icon isn't a consistent location (tabs move), it's far removed from the action needing feedback (the user's eyes are on the cursor; he shouldn't have to look somewhere else after every click), and in fullscreen there are no tabs to begin with.

The result is a UI that lacks feedback and feels unresponsive. This is akin to pages that remove link underlining despite the UI breakage it causes, because they think it looks "sleek".
