I'm not entirely sure how I feel about this statement (and comparison to IE). If anything, Safari is "the new IE" rather than Chrome.
MOST (hopefully the nitpickers pick up the caps lock) stuff in Chrome are drafts or standards.
Sure, Google pioneered/championed some of them, but that's kinda irrelevant if developers voted for those features. There's very little Chrome-specific stuff.
Also, other browsers have vendor specific stuff in them too, yet people rarely fling shit in their direction?
FWIW I also mostly use Firefox for dev because I prefer how some devtool features are designed/implemented.
Most of my cross browser issues in FF were "brief" in the senses that they were bugs that got fixed eventual.
