Details

Device screen is 720x1280 pixels.

If you call window.matchMedia('(max-width: 480px)').matches on DOMContentLoaded, it will return false.
Calling it 1 second later properly returns true.

It started to happen in FF 32. FF 31 and latest mobile Chrome seem to work fine (the linked test page properly displays "true, true", while Fennec 32 shows "false, true".
Should this be moved to Core::CSS Parsing & Computation?

The test case linked from this bug works fine now in the latest Nightly. It was probably fixed by bug 1180267 which landed yesterday.
