My situation is a bit different. I am on some kind of minimalism streak and started to rarely use tabs. It helps with focus and concentration. Would use a browser that enforces a no-tab policy. That's why I enjoy the focus mode so much.
You should check out min browser. it has a mode that prevents you from opening tabs. the design is also very very stripped back. no web extension support but has an adblock and bitwarden integration. it is unfortunately electron based though.
