How do I emulate a CSS print media type in Firefox Developer Edition?


As you can see here, the Developer Toolbar has been removed from the latest versions of Firefox, so I can't run a "media emulate print" command anymore. I would prefer to not have to use Chrome to debug my print styles, so is there any other way to turn on that functionality in Firefox?

Edit: the Web Developer extension is not an option because it only works with <link> tags that have the media="print" attribute -- not print media queries contained in normal CSS files.

Before anyone marks this as a duplicate: I've already seen this question (which does not apply to the current Developer Edition) and this question (which tells me how to do it in Chrome). And I don't have enough rep to do anything other than post a new question.


Solution

  • Firefox has now a simple button for print emulation: Inspect Element, click the page symbol (blue in the picture).

    Isnpect Element view
