Firefox OS Media Query
Firefox OS is an awesome new HTML5-based mobile operating system. Some would says it's epic, I just think it's...super epic. The "native" languages are HTML, CSS, and JavaScript -- it's enough to make a Web Developer weep. Anyways, it's important to know how to target currently released Firefox OS devices with CSS media queries. Here's how!
The CSS
The Firefox OS base media query (for popular released devices) is actually that of a common small mobile phone:
@media only screen and (min-device-width : 320px) and (max-device-width : 480px) {
/* styles go here */
}
This media query accommodates for both landscape and portrait views of released Firefox OS devices.
As Firefox OS is ported to watches, tablets, and other devices, you'll need to keep accommodating other media queries, as you should already. Keep in mind that Firefox OS doesn't have set dimensions, but this will cover to released phones to this point.

Missing images on your website can make you or your business look completely amateur.
Unfortunately sometimes an image gets deleted or corrupted without your knowledge.

But why *would* you target Firefox OS? It seems to me that the best approach is to build a web app that works great across all viewport widths. It’s useful to know which MQ widths are currently used on Firefox OS devices, but hard-coding it into the CSS? I don’t know.
Yes, building a site that looks good everywhere is still the key, but knowing the media query that targets those devices is still important. :)
