I recently came across an awesome browser extension that allows you to hover over text on a webpage and have the name of the font appear in an overlay. It’ll even show you the font size, leading and spacing amount.
FontFace Ninja takes it a step further by allowing you to click the “Mask” button to hide all the images, ads and bothersome clutter to allow you to see only the text on the page. The website has a great intro video to show you exactly how the extension works.
Rounding-off the feature list is a button that allows you to purchase the font you’re interested in with (this feature doesn’t work with all fonts, but they have a pretty good collection of providers for the feature).
FontFace Ninja is free and works with Safari, Chrome and Firefox. It’s perfect for web designers and developers!
