since the update to 71.0b3 (32-Bit) my custom css for multiple tab rows is not working anymore: It is showing only one row anymore; The userChrome.css looks loke this:

  1. tabbrowser-tabs .tabbrowser-arrowscrollbox,
  2. tabbrowser-tabs .arrowscrollbox-scrollbox {
   display: block;


.scrollbutton-up, .arrowscrollbox-overflow-start-indicator, .scrollbutton-down, .arrowscrollbox-overflow-end-indicator {

   display: none !important;


  1. tabbrowser-tabs .arrowscrollbox-scrollbox .scrollbox-innerbox {
   display: flex;
   flex-wrap: wrap;
   display: block;
   overflow-y: auto !important;
   min-height: var(--tab-min-height); /* default */
   max-height: calc(5*var(--tab-min-height)) !important;


  1. tabbrowser-tabs .tabbrowser-tab:not([pinned]) {
   flex-grow: 1;
   min-width: 130px;

max-width: 330px;

   vertical-align: bottom !important;


  1. tabbrowser-tabs .tabbrowser-tab,
  2. tabbrowser-tabs .tabbrowser-tab .tab-stack .tab-background {
   height: var(--tab-min-height);


  1. tabbrowser-tabs .tabbrowser-tab .tab-stack {
   width: 100%;


  1. titlebar-buttonbox {
   display: block !important;
   vertical-align: top !important;


  1. main-window[tabsintitlebar] #tabbrowser-tabs {
   -moz-window-dragging: no-drag;

Hi mein feuerfuchs, you might check on the following forum where more pre-release users hang out and share fixes for userChrome.css rules:

If you get a solution there first, could you report back with a link to it? That would be great. Thanks.
