There are no simple browsers, thus certainly no simple browser for the masses.

If you are on mobile there is Firefox Klar/Focus.

I'm a big fan of https://surf.suckless.org/ .

With some polish and maintenance it could serve as base for a simple(r) browser for the masses. It is essentially a small wrapper around WebKit, which is far from simple, but it has the benefit of great support for modern web features.

Agreed. Firefox99, latest Firefox but party like it's 1999. Web* disabled. Canvas disabled. LocalStorage disabled. DRM-content disabled. Anything else we don't need?

You've inpsired me!

In Firefox:

LocalStorage - about:config Dom.storage.enabled

Canvas - block JS via noscript

DRM - Preferences->Disable DRM content checkbox

WebRTC - about:config media.peerconnection.enabled;

As a side note, noscript has been an eye-opener for how many things are loaded when I open anywebsite! It's been fast, but I've been getting annoyed by guessing what to enable to move past a blank webpage. And WTF is newrelic and why does half of my internet browsing use it?

Newrelic is an application performance monitoring platform, basically give you performance insight on your webapp, so it gain popularity really fast. Really great for identifying performance bottleneck on the server side. Later on, they launched browser monitoring too, so now all webserver that uses newrelic automatically insert newrelic js analytics on every html endpoint.

DOS is simpler than Linux. Lets go back to that.
