Firefox Resolution Tester feature?
I just accidentally discovered a feature I didn't even know existed. What feature? I'll call it the Firefox Resolution Tester feature although I'm sure that is NOT the real name of it. I don't know how long it has been a feature of Firefox... maybe for a long time... but like I said... I just found it in Firefox 30. How do you access it? Hit
CONTROL-SHIFT-m. That's it.
I accidentally discovered it when I wasn't paying attention to which application window I was using had the focus. I thought it was konsole (KDE GUI terminal).
CONTROL-SHIFT-m in konsole toggles the menu on and off. In Firefox it takes the current web page you are viewing and puts a black border around that has a control menu at the top left of that black border. The control menu allows you to pick from several pre-defined resolutions or even add additional presets if desired. Picking a different resolution resizes the view of the page (and increases the black border around it accordingly) to the desired resolution. It also has a screenshot feature (saves to your default download directory and auto-names images something like "Screen Shot 2014-06-01 at 07.42.29.png"). You can also rotate the resolution to simulate a mobile device. It has a "Simulate Touch Event" button but I'm not sure what that does. Anyone?
At work they recently licensed a commercial web content management system that primarily targets larger educational institutions -- OmniUpdate Campus. The web developers (which I am not one) at work have created a nice responsive theme that everyone can use for their departmental websites and it works great. Don't have a responsive site handy? You can try this temporary testing one I made in OmniUpdate. That's just a shell but it'll show you responsiveness.
Anyway, I kind of got off track. Yeah, Firefox. Try
CONTROL-SHIFT-m and enjoy. Can anyone tell me what version of Firefox first included this feature?
