I am a huge Mozilla fan and have used FireFox for many years now. The new update messed up the way I had my browser but I found an addon that let me move things where I wanted them once again. There is one thing I have been unable to fix though - the empty bar underneath the tabs that stretches horizontally for the entire screen. I have unchecked the bookmarks toolbar, addon toolbar and additional toolbar, but whatever bar this is it won't go away. I completely understand the need for the UI redesign and am not complaining. I uploaded a picture here. http://imgur.com/h0f9NRE As you can see, I like the minimalistic look and this bar is trampling upon that look. Once again I'm not complaining about the new UI, but will this bar be removable in a future update?
