Location Notifications (Ex) is a Chrome add-on developed by sammiruan13. It falls under the category of Browsers and is specifically listed as an Add-ons & Tools subcategory. This free add-on allows users to receive notifications of their location sharing friends and more, specifically supporting Google Map location sharing.

The add-on was initially created as a replacement for the defunct "Latitude Notifications" extension for Google Latitude. However, with the discontinuation of Latitude, the developer rewrote the old extension to work with Google+ location sharing. Recently, Google has transitioned location sharing back to Google Maps, and Location Notifications (Ex) has been able to quickly adapt to this change.

To continue receiving location notifications, users are required to install the "Google Maps Location Provider" extension. New users can find additional controls and configurations by clicking on the "Ex" at the top of the configurations page.

Location Notifications (Ex) offers two major features. Firstly, it separates the location source from the notification module, allowing for updates from arbitrary sources. Secondly, it enhances the notification function by utilizing rich notifications and providing options such as enabling a small map on each notification and customizing notification levels and thresholds.

Overall, Location Notifications (Ex) is a useful Chrome add-on for individuals who rely on location sharing and want to stay informed about the whereabouts of their friends.
