Jan 07, 2021At the time, we found that the Chromium engine was secure and the most widely used – that was important to us. Moreover, Chromium was becoming the de facto web standard meaning that if we wanted web pages to not break, we'd have to fork Chromium. Other pieces of code were either unavailable or undergoing significant re-writes (think Gecko).
