Disable elements of the firefox 57 UI for TreeStyleTab

I've added a modification that removes any margin at the top:
#TabsToolbar, #sidebar-header { visibility: collapse !important; } #TabsToolbar { margin-bottom: -21px !important; }
Then go to the hamburger menu > Customization and check "Title Bar" at the bottom left. Then it pretty much looks like FF 56.
I've also changed the style of TSTs in the add-on settings (all the way at the bottom; not in userChrome.css) such that the tabs don't take up as much vertical space and to hide the close box button (and only show it on the mouse-over event):
.closebox { display: none } .tab:hover .closebox { display: block; } .tab { padding-top: 0px; padding-bottom: 0px; }
You can make
.tab
even tighter:.tab .icon { padding-top: 2px; /* reducing it by 2px */ padding-bottom: 2px; } :root { --tab-height: 22px; /* reducing it by 4px */ }
