title: When Firebug is enabled, click events cause Firefox to lag and eventually crash
body: <p>I originally thought this is issue with StackOverflow but later I figured cause of my problem is Firebug. This happens on two different computers, both with windows 7.</p>
  
  <p>What happens is that when Firebug is enabled, clicking things often doesn't work (eg. I can't vote on posts on first try) and scrolling with wheel button also doesn't work.</p>
  
  <p>I tried to download the latest version of Firebug <code>(2.0.16)</code> but the issue persists. My Firefox version is <code>45.0.2</code>.</p>
  
  <p>My question is what can I do to stop that? Disabling the firebug resolves the problem immediately.</p>
