Chrome on the other hand is starting to be a problem because it's too damn fast at implementing new stuff (which are accepted as standard). Web-developers then start using those new features and the code they write suddenly doesn't work on other browsers, because those browser just don't support those new features yet.
That's why we got webpack. That's why we got babel and polyfills. And that's why frontend development sucks a lot lately. Because you have the choice of doing X the easy and fast way, that currently works only with Chrome, because no other browser implemented that yet. Or, you can do it the hard and slow way, that works with all browsers.
And this is not something that I'm pulling out of thin air. This has been discussed several times here, in HN.
