It seems that this issue still occurs in Firefox for focus event.

1. Please download attached file and put it in your samples folder
2. Edit it and try the following combinations :

   e.document.on('focus',TestFocus);
   e.document.on('blur',TestBlur);
   
   OR
   
   e.document.on('focus',TestFocus);
   e.document.on('click',TestClick);
   
   OR
   
   e.document.on('focus',TestFocus);
   

Either blur (first case) or focus event will be fired constantly.

NOTE: the blur and click events seem to work fine.
