// Restore 'Space & Separator' items script for Firefox 60+ by Aris
//
// Default browser scripts always remove spaces and separators from default palette, so
// because of that they are added to an own toolbar now.
//
// - spaces and separators can be moved to any toolbar
// - to remove spaces or separators move them into palette
// - configuration toolbar behaves like a default toolbar, items and buttons can be placed on it
// - configuration toolbar is not visible outside customizing mode
// - default "Flexible Space" item is hidden from palette and added to configuration toolbar
// [!] BUG: do not move spaces, flexible spaces or separator to configuration toolbar or it will cause glitches
// [!] BUG: do not move main 'space'-item to palette or it will be hidden until customizing mode gets reopened

// [!] Fix for WebExtensions with own windows by 黒仪大螃蟹 (for 1-N scripts)
