Published theme

FoxOne

A minimalistic one-line theme for Firefox. The theme collapses the tab bar and URL bar into a single row. Non-essential icons are hidden by default and slide in on hover with transitions. The hamburger menu sits next to the window controls instead of floating in the toolbar.
