Vertikale addon bar's werden nicht mehr angezeigt.

// 'Vertical Add-on Bar' script for Firefox 60+ by Aris
//
// no 'close' button
// 'toggle' toolbar with 'Ctr + Alt + /' on Windows/Linux or 'Cmd + Alt + /' on macOS
// optional toggle button hides the toolbar temporarily, it gets restored on every restart
// 'Vertical Add-on Bar' entry is only visible in toolbars context menu when in customizing mode
//
// flexible spaces on toolbar work 'vertically'
// toolbar can be on the left or on the right
// toolbar is display horizontally in customizing mode
