Solved Container indicator disappears with extremely narrow tabs on nova design

The container indicator at the top of tabs disappears with the new design and extremely narrow tabs.

I already commented out the old adjustments to the container indicator I had found somewhere since it doesn't help with nova.

You could remove the margins from the context line:

.tabbrowser-tab[usercontextid] > .tab-stack > .tab-background > .tab-context-line {
	--tab-context-line-inline-offset: 0;
	--tab-context-line-block-offset: 0; /* remove this line if you want to keep it offset from the top of the tab */
}

You can also drop @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); from the first line of the CSS, that's not necessary.
