GOOGLE FONT PREVIEWER
This very cool tool lets you choose a font from the Google Font API directory, and apply that font to the entire page or a specified CSS selector to see how it looks. Useful when you’re designing/developing a website and want to quickly find a font that will look good. If you always use the same fonts, you can star them for quick access.
Google Font Previewer is an add-on extension for Google Chrome and is available for free in the Google Chrome Webstore. Kudos and many thanks to Pamela Fox for developing this, a guaranteed timesaver for web designers/developers.
