A few years ago, covering browsers got boring.
Chrome had clearly won the desktop, the great JavaScript speed wars were over and Mozilla seemed more interested in building a mobile operating system than its browser. Microsoft tried its best to rescue Internet Explorer/Edge from being the punchline of nerdy jokes, but its efforts essentially failed.
Meanwhile, Opera had shuttered the development of its own rendering engine and redesigned its browser with less functionality, alienating many of its biggest fans. On mobile, plenty of niche players tried to break the Chrome/Safari duopoly, but while they did have some innovative ideas, nothing ever stuck.
