According to the candidate recommendation: A shorthand syntax is offered for media queries that apply to all media types; the keyword ‘all’ can be left out (along with the trailing ‘and’). Source: http://www.w3.org/TR/css3-mediaqueries/#media0 Our documentation currently describes the media type as required: https://developer.mozilla.org/En/CSS/Media_queries
But we have plenty of tests testing that it works, such as: http://mxr.mozilla.org/mozilla-central/source/layout/reftests/css-mediaqueries/mq_print_height.xhtml

(And it's been supported since media queries were implemented.)
Thanks. I just added a line to the documentation regarding this, which should be sufficient for now.
