Aren't we in an era when you literally can build your own browser with everything just you need? I have no knowledge in browsers developement. But in my field it became often easier to make your own tool\app then trying to use third party and make it work for you
My practical approach is to have a microvm for firefox and a bubblewrap “jail” for a firefox instance that runs on the host. Of course, the config options mentioned here are good too.
> Main browser: A restricted Firefox
Mullvad Browser[1] is an example of just that, ready to go for people in the real world who don't have the time or inclination to mess around with random extensions and `about:config` hacking.
Also surprised the blog author made zero mention of the importance of keeping your OS up to date. Its all very well having a patched and hardened browser but not if you're running it on a vulnerable OS.
