This browser plugin is useful when you have a Garmin GPS device, as used for various outdoor sports, and want to transfer files to a website for sharing fitness data, like connect.garmin.com. It has the same methods and properties as the official Garmin Communicator Plugin, and can be used to transfer GPX files (Geocache Descriptions) to your Garmin device using the official Garmin Javascript API. The available functionality depends on the device you use.

Various Edge and Forerunner devices, and several fitness websites are supported (see the garmin-plugin homepage).
