<p>Firefox 6 on Fedora 15 on an aspire one netbook.<br>
Clicked help->about to see what version I had. About window pops over main and has no close button or window top bar "X" to close.<br>
WTF!?!?<br>
I can right click and select close.<br>
The loss of common use across windowed applications is a design FAIL in my mind.<br>
Ubuntu have same issue with Unity?</p>
