Can't agree more. The main thing that keeps me using OSX is Adobe Creative Cloud.

I'd mention aesthetics, but the current Linux distros look quite good, plus they're customisable.

I used to work with a developer who'd preach the "IceWeasel is the ultimate browser" gospel to us. I guess this makes your argument somehow more valid:)

OS might be hard, as Win and Mac have their own browsers, so my first guess would be Linux or security focused builds of Android. This doesn't sound like enough exposure to make a significant/disruptive change.

I expect Mozilla to be more active in this area though. Yes, performance is important and I switched to FF recently too, but I'm still using Electron powered apps on my MacBook.

What's more plausible is a situation where Chrome for some reason (ekhm... privacy?) loses market share to FF/IE/Safari. Having more competition will make my browser better, regardless of my choice.

Look faster, but still buggy. I've tested it on latest chrome dev and the ball doesn't render well.
