Overlaps minimize button

[clokep]

If you make the window small (or your default size is small, like mine) the button overlaps the Minimize button, click on the "Instantbird button" clicks through to the minimize though. Not sure what should be done, maybe have a minimum size?

That would be mozbug 575200. Minimum size isn't possible yet because the platform doesn't support it. I don't think we can do CSS for "if window width is less than X hide this element" either...
