Hi carricka, the space above the top of the toolbar is there for some space to drag the window.

• [Bug 1005712 - FF29 on Windows wastes vertical space in the "title bar". ]

However the space on the bottom can be customized by adding a toolbar with the classic theme restorer add on.

I hope this helps.

Hi there and thanks for your reply.

The classic theme restorer add on doesn't solve it and, in addition, causes the top half of the tabs to disappear (I have them loaded at the top of the screen). The classic theme restorer add on also seemed to stop Firefox dead in its tracks, so I've disabled it and got back to where I was before loading it, though it took me a few attempts to get Firefox to load.

Hi carricka, Thank you for your response. Let's try something else: I added a screenshot with the classic theme restorer. I want to make sure I know what you mean by the toolbar having a missing space or overlapping on the main page. Where have you put your toolbar when you click on the three horizontal line menu and clicked on customize?

Thank you!
