Latest Firefox disaster... excessive tab height.

Ok,

But if I'm only interested in the snippet that take care of the tabs... Where can I get it in your code @Ghot ?

I use a very simple css just to reorder the Menu Toolbar, Bookmark and Tabs. That's all...

My current file.

Code:

/* note : these are code snippets copied from elsewhere*/

/* MAKE SURE THIS IS THE FIRST LINE         */
/* Menubar on top                         */
    :root:not([sizemode="fullscreen"]){ --uc-window-control-width: 0px !important }

/*note this used to be different before 90*/
/*menubar location-position*/
    #toolbar-menubar{
    position: fixed;
    display: flex;
    top: var(--uc-titlebar-padding,4px);
    width: 100%;
    overflow: hidden;
    }

/* order - Bookmark bar beneath URL bar, Tabs beneath URL bar */
    .titlebar-buttonbox-container > .titlebar-buttonbox{ height: 100%; }
    #titlebar{
    -moz-box-ordinal-group: 2;
    -moz-appearance: none !important;
    --tabs-navbar-shadow-size: 0px;
    }

/*https://www.userchrome.org/firefox-89-styling-proton-ui.html*/
/*** Tighten up drop-down/context/popup menu spacing ***/
    menupopup > menuitem, menupopup > menu {
      padding-block: 0px !important;
    }
    :root {
      --arrowpanel-menuitem-padding: 0px 0px !important;
    }

/* navigator location-position   */                                                        
#navigator-toolbox{ padding-top: calc(22px + var(--uc-titlebar-padding,5px)) !important }
    :root[sizemode="fullscreen"] 
	#navigator-toolbox{ padding-top: 5px !important; }

/* Bookmarks menu padding                   */
    #BMB_bookmarksPopup .subviewbutton {
    padding: 0.2em !important;
    }
/* make border around urlbar              */
    #urlbar-background,
    #searchbar {
    border-radius: 4px !important;
    border: 1px solid #8D8D8D !important;
    }
	
/* icons spacing                         */
     #main-window[uidensity=compact] {
     --toolbarbutton-outer-padding: 2px !important;
     }

/* TABS: height */
:root {
 --tab-toolbar-navbar-overlap: 0px !important; /* fix for full screen mode */
 --tab-min-height: 36px !important;
}
:root #tabbrowser-tabs {
 --tab-min-height: 36px !important;
}
#TabsToolbar {height: var(--tab-min-height) !important;}
