I feel like there is no web browser with a sane default configuration that I can recommend to other people. All browsers are preconfigured in a way that harms the privacy of their users or include services that no one wants such as Pocket and BAT.

Here are my problems with some popular browsers.

• Mozilla Firefox: Pocket integration, no ad-blocking without extensions.

• Brave: Everything related to crypto. Also its start page is horrible.

• Chromium: No ad-blocking without extensions and soon Manifest v3 will cripple all content blockers.

Now, these suboptimal defaults wouldn't be such a big problem if the configuration files were easy to backup and restore and respected the XDG base directory specification.
