Mess with Tree Style Tab styles to get close to old school feel. (Also, some random other changes)
These styles can be entered by going to:
  Add-ons -> Tree Style Tab (Options) -> Advanced -> "Extra style rules for sidebar contents" Text Box
*/

/* Shrink tab size and keep pinned tabs from getting squished. */
:root { --tab-height: 25px !important; }
.tab:not(.pinned) { height: var(--tab-height) !important; }

/* Fade out unloaded tabs */
.tab.discarded { opacity: 0.65; }

/* hide close tab buttons (X) */
.closebox {
    display: none !important;
}

/* hide bottom new tab (+) */
button {
    display: none !important;
