Firefox is a nasty CSS hack, but it does work, and that's something to
be happy about.
Microsoft makes it easy; Firefox developers have said they do not want
it to be "easy".

From Robert O, reflecting Mozilla's policy: "I don't want Web authors
to have easy access to information about screen pixels.
They'll try to defeat our zooming or size things to screen pixels, which
we don't want."
WebKit and MS already diverge from Firefox in handling of
window.innerWidth/innerHeight and window.screen properties.
That's not news.
I'd really like to see a resolution to this issue. The hacks I'm using
just aren't stable in the long term.
I'd prefer the property were just exposed to the DOM via window.screen,
as MS has done it,
but I'm ok doing CSS media queries.
It's just that media queries require something of a brute-force of case
statements;
I have about ~12 media queries to handle Firefox, all just repeating min
media query,
trying to narrow down the resolution.
Long-story-short, can we please expose some of the CSS pixel scaling,
either through window.devicePixelRatio,
through CSS media queries on device-pixel-ratio, or through the
window.screen object, in a way similar to
how MS has done it
Anything will work.. I just need one.

Hi Simon,
I guess you could use the media query listener defined in
http://dev.w3.org/csswg/cssom-view/#the-mediaquerylist-interface
We support that on trunk now. This of course means that we will need
to reevaluate the CSS when a pinch zoom ends, which we might be doing
already given media queries such as @media all and (min-width: 200px).
Cheers

Hey Oliver!
If you are saying that device-pixel-ratio should include the user
scaling, then I can push that for Qt, but I would really like seeing
it supported by iOS as well for compatibility reasons. If you create a
bug for that, please cc me.
There's a problem with that, which is that the author can assume (possibly
erroneously) that device-pixel-ratio doesn't change for the life of the page.
However, the zoom level can change often, and there's no notification that the
author can register for that will tell them when the zoom level changes, and
thus when they'll need to redraw their canvas contents.
