Interesting synopsis and confirms something I've always felt: There was never really a plurality of web browsers, there was always one that held an outsized majority vs the rest and drove web development practice. The closest, perhaps, was a brief period before Chrome became dominate and IE was waning fast, where I believe Safari, Firefox, and Chrome held approximately the same market share vs IE, which would be in the 2010-2013 era (peak Webkit was 2012), which I personally regard as one of the most interest times to be both on the web and be a web developer, it was also before Chrome forked Webkit fully IIRC.<p>FWIW, I know having Chrome / Chromium as the overwhelming majority browser is not great, if for the sheer fact competition keeps everyone "honest" in a way, but they are by far the most "benevolent" from a developer perspective. IE was truly both stagnant and terrible.<p>EDIT: that's not to say I approve the Chromium dominance, as a daily Firefox user especially, but I would be lying if I said, from a developer perspective, that Chromium hasn't been pretty good so far on balance. They do innovate. They do push new features. They do usually support the latest specs. Though again, I don't approve of it being so dominate, I'd prefer a plurality. Its a shame that Microsoft didn't use Firefox as its base for new Edge
