I suspect that a lot of the “alternative browsers” I want to build can actually be done using the WebExtensions API. Unfortunately, I’ve not paid as much attention to this, so I need to deep dive.
Some of these example extensions are cool!
One could build a modular, inter-operating set of WebExtensions to adjust any browser to be the tool a user needs to perform their particular kind of research.
