Development of IE stagnated after Microsoft put Netscape out of business, because Microsoft got complacent, until Mozilla resurrected the remains of Netscape and saved the web. Then Chrome came along and Google convinced almost everybody to switch to it, including competing browsers like Opera. Chrome was originally based on Safari’s WebKit (a fork of Konqueror’s rendering engine KHTML), but then Google forked it (Blink) so they’d maintain control of it.
From what I’ve heard, most web devs only test on Chrome since every browser other than Firefox and Safari is based on it. And nobody seemed to care until very recently, because they didn’t think a browser based on an open source project could possibly be a problem.
I’m honestly not surprised any of this happened, and I stick to Firefox and Safari myself, but I do worry about the ramifications of getting a real Chrome on the iPhone and iPad. I never liked Chrome and don’t want to be forced to use it.
Yeah, I know maybe like two other people who use Firefox. Everybody else uses Chrome. And it’s been that way for the last decade or so.
I still prefer Firefox, but I worry about its future because most people, including web developers, just don’t care.
