Tor Browser: middlemouse.contentLoadURL should be disabled per default, because it's way too easy to trigger it accidentially

I suggest middlemouse.contentLoadURL to be disabled per default, since I always accidentially middle mouse click at some point when scrolling, even more so with my trackpoint. In my regular firefox I have disabled this behaviour, but it's all too easy to forget with the tor browser.

Because it can be easily enabled by people that rely on it and because text middle mouse pasting still works as expected when this is disabled, I suggest middlemouse.contentLoadURL is set to false (current default: true) to avoid users accidentially going to URLs which may reveal their identity.

(The problem really isn't the middle mouse pasting by itself, but that firefox/tor browser will also instantly load up the page without any additional confirmation)
