Unless you personally authorize sharing your precise location with a website, the site guesses based on your IP address. Your IP address generally is assigned by your service provider (or if you are using a public hotspot, the hotspot provider). Is there a particular site you want to have permission to access your location? If so, you can pre-authorize it this way: While you are on a page on the site, call up the Page Info dialog using one of these methods: * Ctrl+i (for Mac, Command+i) * (menu bar) Tools > Page Info * click the lock icon in the address bar, on the drop-down click the > button, then at the bottom click "More Information" When the dialog comes up, click the Permission icon at the top to show that panel. Near the top, you'll find "Access Your Location" and you can uncheck the "Use default" box and select the permission you prefer.
