Only restores half the old look, you still have to disable nova in the about:config to actually get the old look back.

this theme is only part of it. what most really want is about:confg -> browser.nova.enabled = false to get rid of the rounded corners (for now)

why you only offer a half solution to the problem you caused ? i just want my old tab back.

Why all tabs are rounded? In contrast to square tabs on preview...

Everything is rounded and doesn’t look like it did in the preview. That’s exactly what I wanted to fix with this theme.
