I find it good! And the frequent "Oops, there is a problem! There was a problem with the geolocation..." could be solved with manual input of location! the frequent popups is owed to internet unstability i guess.
It works Ok, there a little issue when you try to select Manual Location. If you typed a name that was not found, it does not show an error message, neither inform you about something happened; it only reverses the setting to Automatic Location.
If you type the location and it finds it, it works and setting is stored, so the thing is about alerting the user and refreshing the UI if an error occurs trying to locate the place on the input.
Extensions is very nice but there's an issue. (As I don't see any related website I have to report the issue here)
I choose Manual for the location, typed in my location, and Clicked Submit. After refreshing the page the Option Automatically is choose again. It would also be nice if I could see which Place Geolocation choose for me.
