Looks to be the best nord theme on here (I tried a LOT). One small tweak if it's possible, dim the inactive tab a little. I come from chromium and used a nord theme there which did similar, and it made all the difference.

It would be great if you can also theme the new tab page.

Beautiful, but it will perfect if new tab have darker background, can i post this as request :D

Good. Just needs to theme the new tab page.
