Decades after starting the web browser wars, Microsoft has given up its proprietary Edge web browser in favor of its open-source based rival Chromium.

Opening Web pages in new tabs within a single browser window will not allow you to achieve the cascade effect.

To show off what EdgeHTML can do, Microsoft has built a browser using predominantly JavaScript, HTML, and CSS. Next, the company released the app on the Windows Store and the sample code on GitHub.

For San Francisco programmer Stanislas Polu, that wasn't good enough, so, he created Breach -- an open source modular web browser designed to allow anybody to tweak and modify it on a whim.
