Browser Support and Ordnance Survey Compass

The Ordnance Survey Compass application is supported by most modern browsers, with the exception of Opera 11 (see table below). The application is javascript-heavy and although the code has been optimised for individual browsers, there are clear differences in responsiveness and execution speeds. Google Chrome is the most responsive and 'snappy', followed by Safari and Firefox.
