I would like to have all windows in chromium (on linux) open without the toolbar/tab-bar displayed. My research so far has found that when opening a new window with window.open in javascript, the toolbar can be hidden by passing toolbar=0 as an argument. Also, in the javascript console, I can see the value of window.toolbar is BarProp {visible: true}. However, trying to set this value (by executing window.toolbar.visible = false) has no effect - the value remains true and the bar remains visible.
I would like to know two things - How can I hide the toolbar in the current window (not by opening a new window)? - Once that is solved, how can I cause that to be done automatically when each new window is opened?
