Just about perfect, I'd love to see a near identical version of this where the active tab is outlined in a white or at least lighter gray.

Great theme! Really gives FF a fresh, modern feel.

Pretty nice theme although I have two issues, this doesn't affect context menu (which i sorted out using userChrome) and the new tab page doesn't obey dark mode rules on Windows. Other pages like about:suppot, preferences all follow dark mode rules. Any idea what would be wrong?
