Very simple in Firefox (tested in Firefox 60.4.0.esr - any later check toolkit.legacyUserProfileCustomizations.stylesheets etc.):
- use userChrome.css to display ALL tabs side by side:
profile/chrome/userChrome.css :
tabpanels {
display: -moz-box !important;
}
tabpanels > notificationbox {
-moz-box-flex: 1;
border-width: 2px !important;
border:solid #888;
}
- with extension like last_selected_tab AFAIR, or your own, to have content-secondary, handled - then hide any browser of other type with styles as well (as by default you have only: tabpanels > notificationbox > browser[type=content-primary] - being the active tab). :)
