I hope they didn't screw it up as bad as Apple did with Safari: http://www.phoboslab.org/log/2012/09/drawing-pixels-is-hard
Edit: judging from some comments in the source, the Canvas element still uses a low resolution, so the test case should work as expected in any case.

}Prior to that I used the "retinizer" app and the about:config hack to disable acceleration, but performance was really bad. Since running nightly, it has been fully retina enabled and smooth.
Left is Firefox, right is Chrome. Nothing special done to either. MBP is at the factory resolution. Very ironically, the screenshot at half-size looks better on my 24" Windows display than it does on the actual MBP does, presumably as Chrome is doing some resampling to downsize it. Look at it at full zoom to see what I mean.
I'm doing active web development on a number of browsers across a number of devices (Macs, Windows, iOS, Android), and Firefox on the Mac is easily the worst of the lot, by a rather large margin. I would easily notice if the whole screen looked like it - text is blurry and awfully aliased, to the point that it's jarring to read. I spend most of my time on Windows, which by most accounts has less beautiful text rendering than OS X, and switching over to Firefox on the rMBP feels just awful.
Given that I spend 99% of my day looking at a 94 DPI screen, I don't think it's too much to ask that the same application on my 220 DPI display not look like I'm playing Minecraft.
Could you write more what is wrong with firefox on this screenshot?
I don't know if you're being hyperbolic, but that feels like a really minor thing to me.
Direct comparison of some of the more egregious examples in Firefox (Top) vs Chrome (bottom). Look at the tab title, the text in the dark grey nav bar, the aliasing on the back button, the aliasing on the text, the aliasing on the edge of the "O" in the Google logo, and the aliasing of the text under the buttons.
I'm not sure what they could have done beyond making sure Cocoa's text-rendering routines produce the right "retina" output. Which they do. Firefox (and Chrome) do their own text rendering and rasterizing, as far as OSX can see it they give it a big image to display. Not much OSX can do with that.
Windows XP had abysmal support for high DPI which usually resulted in broken UI layout. Vista introduced "DPI virtualization" requiring you to declare and provide explicit support for variable dpi in your application. Otherwise it is run at 96 DPI and raster scaling is applied. This prevents any UI layout issues but results in a a blurry image. I guess Apple uses the same approach: if your app has no explicit support, it runs under raster scaling.
whole thing looks like this.

The version number is meaningless. What is meaningful, however, is getting millions of people to help test beta browsers. If Chrome is your browser of choice then help test the Canary builds (https://tools.google.com/dlpage/chromesxs)
On Windows, Chrome does a good job auto update in the background. Firefox am not so sure but they too are working on some kind of auto update. Good for them, not being stubborn, and implementing a good feature that their rival has.
Good for Chrome that they aren't suing others trying to implement auto update. :-)
