I don’t really think the current setup is too bad. Chromium being open source means anyone can fork it and make their own better browser without having to write everything from scratch.

Personally, I use Vivaldi. To the best of my knowledge Google can’t spy on me, they have plans for mitigating Manifest V3, and it has many useful extra features such as tab splitting and separate workspaces. It’s made to be super customizable and from my experience the interface stays mostly the same between updates - something that annoyed me a lot about Chrome/Firefox. It can be a little rough around the edges sometimes, but I love using it.

This is the power of FOSS. By default it treats the end user with dignity because you aren’t a tool to extract value from anymore.
