Fixes for v133. Url bar and tabs overlap

[Astrm]

After updating to Firefox v133 the one line theme does not work as expected. The URL bar and the tabs overlap each other and transparency is also a mess.

Please suggest the changes in CSS which will help revert it to the good old one line theme.

For the layout problem, change titlebar to TabsToolbar in includes/cascade-responsive.css on line 17,
and add

  #toolbar-menubar {
      order: -100;
      flex: 1 1 999999px;
  }

This work for me.
I am not good at css, so the code looks bad.
It seems firefox changes titlebar to TabsToolbar and toolbar-menubar.
