While both Mac and Windows computers have built-in functions that allow you to take a screenshot of your desktop, Firefox has a plug-in that does one better: it can take a screenshot of an entire webpage. Instead of taking multiple screenshots and piecing them together to show one page, you can download and install the Screengrab plug-in to do the same.
How to Use Screen Grab (Firefox)
Screengrab is a Firefox extension that makes it easy to save a web-page as an image – it’s a screen capture tool for Firefox! With it, you can save anything that you can see in a browser window – from a small selection, to a complete page. You should really download it right now.
Basically Screengrab! let’s you take what you want from a web-page: the entire scrollable document, just the visible bit, or a draggable selection. Screengrab will even save just the contents of an individual frame. Screengrab captures Flash and Java applets as long as you have Java installed.
To use it, just right-click a page to bring up the context menu and look at the options under “Screengrab”. It’s pretty self-explanatory! (if you don’t see the menu then something must be broken – better send me an email). You can save it as jpg or png. It can also capture Flash and Java applets.
Navigate to the website that you want to take a screenshot of. Once it has completely loaded, right-click anywhere on the page. A menu will pop up, and at the very bottom, you should see “ScreenGrab” as the last option. You have a 3 different ways to take a screenshot with ScreenGrab:
Save a Screenshot of the Entire Page
To grab a screenshot of the entire webpage, choose “ScreenGrab” > “Save” > “Complete Page/Frame” A “Save Menu” will pop up to save the screenshot. You can rename your screenshot and change the location to save it. You can also change the format from PNG to JPG using the drop-down menu.
Save a Traditional Screenshot
You can use ScreenGrab to take a traditional screenshot, as well. Right-click on the webpage, and choose “ScreenGrab” > “Save” > “Visible Portion.” This will capture a screenshot of just what is seen on the screen. When the “Save Menu” pops up, name your screenshot and save it to your preferred location.
Save a Section of the Screen
ScreenGrab can screenshot just a section of a webpage, the same way that Mac can. To do this, right-click and choose “ScreenGrab” > “Save” > “Selection,” and the entire page will turn a light purple shade. Holding down your left mouse button, drag your cursor over the area that you want to cap, and you will see a box appear as you go. When you have capped the area you need, let go of the mouse button and the “Save Menu” will pop up – name and save your screenshot, and you’re done.

You can do all three of the above screenshot methods, but instead of saving directly to your desktop, you can choose to have the screenshot saved to your clipboard. This is a good option for those who would rather paste the screenshot into a paint program and make some changes to it before saving. To use copy instead of save, follow the same exact instructions, except choose “Copy” instead of “Save” after choosing “ScreenGrab.” If you are a webmaster or blogger, this Firefox plugin is for you.
