The editor relies on the support of SVG Fonts [1]. Until the support in
mainstream browsers matures, please do one of the following:

- Download Google Chrome [2] and subscribe to Developer preview channel [3]
- Download the latest nightly build of Webkit [4] and if you are running on
Windows you also need Safari [5, 6]

Note: To track the progress of the support in Firefox follow Bug 119490 [7]
