[Dragtotab] MileWideBack - close tab when there is no back history

[Tom Kennedy]

I love MileWideBack, thank you.

I used to have the Back Is Close extension installed also, which meant that if I click the edge and the tab has no back history, the tab will close.

The problem is that Back Is Close has not been updated to Firefox 2.0.

So I figured out how to put that feature into MileWideBack, and it works.
Please consider adding this feature, to make it easy for others also.

By the way, I wrote two extensions myself: Addictive Typing Lessons, and Numpad Typing Drills.

Below is the code to add the feature:

  onClick: function(event) {
    if(event.button == 0) {       
      if(gBrowser.canGoBack) { 
          MileWideBack.left(event);
      }
      else {
          gBrowser.removeCurrentTab();
      }
    }
