Other toolbars will only be visible when you move your mouse over one of these two toolbars.

Problem with hiding the tabs is that hovering the mouse over them hides them again! Oops... Also, when saving, it gives an exception:
[Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAULURE) [nsIDOMEventTarget.dispatchEvent]" nsresult: "0x80004005 (NS_ERROR_FAULURE)" location: "JS frame :: chrome:/stylish/content/common.js :: anonymous :: line 184" data: no]
And then it won't save...
