I would like to control the positioning of the favicon and text which appears on the tabs. I'm hoping this will be possible by using userChrome.css. Also, would it be possible to reduce the height of the background behind the tabs with userChrome.css?

My goal is basically to reduce the height of the tabs and the background behind the tabs.

Thanks

You can find the relevant code for the tab bar height in this file that you can open via the location bar.

  • chrome://browser/skin/browser.css

I use code like this to adjust the height: 

@namespace url("https://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

/* Tab bar: adjust height - chrome://browser/skin/browser.css */
#tabbrowser-tabs,
.tab-background-start[selected=true]::after,
.tab-background-start[selected=true]::before,
.tab-background-start,
.tab-background-end,
.tab-background-end[selected=true]::after,
.tab-background-end[selected=true]::before {
  min-height: 24px!important;
}
#tabbrowser-tabs {height:26px!important;}
#tabbrowser-tabs toolbar button > .toolbarbutton-icon { padding-bottom:2px !important; }

For the icon and the text you can modify the padding or margin of those elements with these selectors: 

.tab-text {padding-bottom:3px !important; }
.tab-throbber, .tab-icon-image  {padding-left:2px !important; }
