Love fonts? Then FontFaceNinja will be your new best friend online.
It let’s you find and download fonts you like on any website! It’s free to download fonts, but the site encourages everyone to buy fonts they like. They are building a blacklist for licensed fonts.
To use FontFaceNinja, you install a browser extension that allows you to identify the font used on a website. It gives you the name, size and also the line spacing of the font. The plugin lets you hide any pictures to focus on fonts against a blank background.
