I tried to switch to Firefox, but was stymied by a bug where Firefox consumes 100%+ CPU on MacBook Pro Retinas.
Firefox is basically unusable with this bug; Facebook takes forever to load, and even Reddit r/firefox shows "A webpage is slowing down your browser" bar at the top.
But apparently this has been going on for 2+ years and Mozilla hasn't been able to fix it.
Given rMBPs (I would think) would be a fairly large market share of people who work at Mozilla or use Firefox, it's both concerning and surprising that a bug of this proportion has gone on so long.

Edit: Jeff from Mozilla has reached out. I sent him a perf log and a screenshot. Tracking here: https://bugzilla.mozilla.org/show_bug.cgi?id=1494186
