Choose Wisley for Mac lets you select your browser on-the-fly
All you need to do is simply drag and drop your browsers into the application window. A maximum of 5 different browsers can be stored, and browsers you no longer need can be removed by dragging them out of the window. Mac OS X 10.6 Snow Leopard is required. Older versions are not officially supported and may cause system crashes.
Choose Wisely is Freeware inspired by the $12 shareware Choosy and developed by Christoph Zirkelbach.
