I've been playing around with using "base browser" as a stopgap and it's really all I want in a web browser - no branding, no labs, no telemetry, a few sensible safety defaults, but nothing that degrades general experience (and with the ability to go hyper restrictive if desired)
The one downside is that you have to compile this browser from source, and its not a standalone project - its the firefox fork that serves as the pseudo-base of the Tor and Mullvad browser.
