whereami extension

An extension that makes the Firefox browser location-aware. The extension supports multiple ways to determine your current position:

  • via Plazes API -
  • via attached GPS (using GPSBabel to access the device)
  • by manually providing your location (address or coordinates)

The location context in the browser can be used to make sites automatically location-aware e.g. when visiting a maps site - it automatically shows your current location to start. See list of supported sites below.

    Firefox 3 does not support your extension, "because there are no secure updates available". This is surely a question of trust. I would trust you, but what about many users who will not.

    Your extension and the web standards growing around it are very interesting.
