In the latest version of comodo dragon (Version 28.1.0.0) the geolocation is not working.
It returns a message:
“Network location provider at ‘https://www.googleapis.com/’ : Returned error code 403.”
I searched google for it and it appears to be a building and packaging error, because the browser is built with wrong api keys.
