I came here to suggest Vivaldi. I’ve been using it for nearly two years as my primary browser. It’s not perfect, but no browser is. However, it’s the only browser I’ve found that treats It’s users like an adult and lets them setup the browser the way they want.

Vivaldi is the true successor of Opera, more so than the Opera we have today.

Opera is run by some random company but Vivaldi is developed by the original Opera developer.

But Opera is still useful because it has a VPN (proxy really) built in so that you can reach sites blacklisted by various public Wi-Fi access points.

It's the one I used. While people complain it's not open source, it's about 99.9% viewable from the point of view as source code.
