In conjunction with Mozilla’s announcement for Web Open Font Format (WOFF) and continuing wanky tradition of removing vowels from web app names, CSS Ninja has created, Font dragr — an experimental web app that uses HTML5 & CSS3 to create a useful standalone web based application for testing custom fonts, once you visit it for the first time you don’t need to be online to use it after the initial visit. It allows you, in Firefox 3.6+, to drag and drop font files from your file system into the drop area. The browser’ll then create a data URL encoded copy to use in page and render content in dropped font. It allows you to drag & drop your truetype (ttf), opentype (otf), scalable vector graphics (svg) or Web Open Font Format (WOFF) fonts.
