Unlike Mozilla, I think Chromium based browsers are the most evolved ones and come in different flavors. Firefox under Mozilla Mozilla open source project and Google Chrome under Chromium. And we almost forget that these popular browsers are built on an open-source project. This isn’t our fault, because most people heard only these two names under the browser category. While choosing a web browser, most of us stuck with Google Chrome or Mozilla Firefox.
Although the popular one, Google Chrome itself a chromium based browser - an open-source project and the browser source code released and maintained by the Chromium Project started by Google.
Why we don’t even bother to try web browsers other than Google Chrome and Mozilla Firefox.
