Try Firefox’s new screenshot tool
Last issue, when we were summarising the best new features in Firefox 55, we lamented the fact that we hadn’t yet seen the promised Screenshots tool, which is being rolled out to users gradually. Since then, we’ve discovered a way to activate the function whether Mozilla likes it or not – assuming you can’t see it already. Type about:config into your address bar, press Enter and agree to the warning. Then search for ‘extensions. screenshots’ and ensure that both of the matching preferences are set to ‘ false’. If they’re not, double-click them to change their values. Once you’ve done that, the Screenshots button, which looks like a pair of scissors cutting out a shape, will appear on your toolbar.
To capture a screenshot, click the button and click or drag on the page to select the desired area. Click Save to copy the screenshot to your clipboard or Download to save it to your hard drive. Grabs are saved to the Firefox Screenshots site ( screenshots.firefox.com) automatically. You can set them to disappear after a specific length of time or delete them manually.
