HELP! My line of tabs run together with no separation between them.

I copied a custom CSS to get rounded tabs and tabs on bottom. 

/* Firefox Quantum userChrome.css tweaks */
/* Github: https://github.com/aris-t2/customcssforfx */

:root {
  --tabs_toolbar_color_tabs_not_on_top: linear-gradient(#f9f9fa,#f9f9fa);
  --tabs_toolbar_border-tnot_normal_mode_size: 1px;
  --tabs_toolbar_border-tnot_normal_mode: var(--tabs-border-color);
  --classic_squared_tabs_tab_text_color: black;
  --classic_squared_tabs_tab_text_shadow: transparent;
  --tab-min-height_tnot: 32px;
}

:root[uidensity=compact]  {
  --tab-min-height_tnot: 28px;
}

:root[uidensity=touch] {
  --tab-min-height_tnot: 40px;
}

Unfortunately that doesn't work and I am looking for more of a divider between the tabs. Almost like a border around each tab so they don't all run together.
