--menubar-height: 10px;
--bookmarkbar-height: 18.3px;
--tabbar-top: calc(var(--menubar-height) + var(--bookmarkbar-height) + var(--tab-min-height) + 5px); /*89+*/
}

#TabsToolbar {

width: 100vw !important;
}
#main-window:not([chromehidden*="toolbar"]) #navigator-toolbox {padding-bottom: var(--tab-min-height) !important;}

and if you don't like "The Status Bar" flickering away down at the bottom of your screen, add this line to your chrome file...

#statuspanel {
display: none !important;

}
