allow to use geolocation for a website for which I previously refused it
Chrome Version 23.0.1271.64 should show you a location denied icon to the right of the address bar, which when clicked will show you clear options.
Alternatively you can find the setting under settings->advanced->content settings->location->manage exceptions
Just use this cool instructions. I hope it will be useful.
