How do I hide Container icons in tabs?

[alessandromassone]

I'm trying to hide the "Container" indicator/icons in tabs — the element controlled by .identity-color-toolbar in Firefox's horizontal tabs. I don't need them to show since I have a custom Container set for each Sidebery panel — which makes all the indicators superfluous.

I haven't found any documentation on how to customize them with the built-in Styles editor. Is it possible?

I hid mine by adding this to the style editor in Sidebery's settings:

/* hide container indicator */
.Tab .ctx { display: none !important; }
