How to Create Screenshots in Firefox
Firefox's developer tools have been well-noticed due to the wealth of functionality they provide, but one tool you don't hear too much about is Developer Toolbar, which looks much like the console but serves a completely different purpose. One of those purposes is allowing developers to create a screenshot of the current page in Firefox. Let me show you how!
The first step is opening the Developer Toolbar with SHIFT+F2. Once the Developer Toolbar is open, you can direct Firefox to take a screenshot of the current viewport with the following command:

screenshot homepage.png
You can pass an additional configuration argument to get a screenshot of the entire page of the page:
screenshot homepage.png --fullpage
When these statements are executed, the image is saved to the browser's default download directory!

![MooTools: Set Style Per Media]()
I'd bet one of the most used MooTools methods is the setStyle() method, which allows you to set CSS style declarations for an element. One of the limitations of MooTools' setStyle() method is that it sets the specific style for all medias.

I'm a huge fan of using subtle effects like link nudging (jQuery, MooTools) to enhance the user experience and increase the perceived dynamism of my websites. Trust me -- a lot of little things are what take websites to the next level.
I prefer to use the Firefox Dev Tool and enalbe the screenshot feature and click on the gear that do a fullscreen screenshot in a fast way :-D
Nice article, I think there’s a typo there, it should be F12 and not F2
In my case, I used the shortcut key shift + f2…
And the command was
screenshot homepage.png --fullpageI use Firefox 34.0 (PT-BR ‘portuguese/brazil’)/Windows 7
It was shift+f2 for me as well.
Nice tip David! :)
For info, the screenshot command is also available as a button in the devtools (for those who prefer clicking and have the devtools opened anyway).
It’s not available by default, but it’s just one setting to turn ON and it’ll be there all the time afterwards:
– open the devtools
– click on the gear icon (toolbox options) in the top-right corner of the devtools window
– look for the “Available Toolbox Buttons” section and check the “Take a fullpage screenshot” box
– now you have a new icon in the devtools toolbar, it looks like a camera, just click it and you’ll have a screenshot of the current page in your download folder!
some corrections
1. –fullscreen is not an option it’s fullpage
2. it doesn’t work in inspect element window you need to open developer toolbar (in mac shift+fn+F2)
it could have been awesome if it worked in inspect element window as well.
By the way is there anyway I can invoke this from my Javascript code?
This is really great! So far I relied on Print Screen button on keyboard but this far more efficient and flexible.
You can also try Lightshot. It’s a tiny and very helpful tool for Windows/Mac. It’s activated with the regular Print Screen button on the keyboard, but it has multiple additional options: save, upload, share on social networks, copy, add text, add lines, etc. You can crop from the screen just what you need.
Fireshot can be a best option to capture any part of the webpage, its very easy to use.
With the
--fullpageoption I would expect to get a screenshot from header to footer of the webpage even when it’s a page which is multiple vertical screens tall…Or do I just misunderstand the functionality of the
--fullpageoption?I’m using FF 40.0.3.
Hey – this works:
screenshot --fullpage trueThen I get a fullpage screenshot of a webpage with multiple vertical screens. It just saves then as true.png :)
