I have firefox 24.0, firebug 1.12.3, and web developer 1.2.5 I have noticed that the @media print css is being ignored when printing. Go to http://www.usabledevelopment.com/examples/media-css.html. (This is an example that I found to verify what I was seeing. It is not my web site) You will notice that there is a @media print in the style within the head. If you select the body in firebug, it shows references to the @media screen in the style pane. If you go and check the menu item "Display Print Styles", nothing is shown in the style pane for the body element. I would like to know what is going on.
