Browser a dime a dozen and one would think the differences are almost zero. Unfortunately, that's not quite true.
CentralPlanner uses the latest technologies and demands a lot from the browser. To enjoy the full comfort, we recommend to use a modern browser based on Webkit technology, like the browsers of Apple (Safari) and Google (Chrome). But even with the latest version of Mozilla Firefox the use of CentralPlanner should be unrestricted.
We advice only against using CentralPlanner with Microsoft Internet Explorer. In particular, the older versions (before version 9) often do not work accordingly to the web standards.
