GrabMyIP by vexxed

GrabMyIP v2.2 allows users to retrieve their IP address, city, country, and ISP information when clicked. When the browser action is clicked, the add-on sends a fetch request to https://ipinfo.io/json to retrieve data in JSON format. The response is then checked for errors and the data is parsed and stored in the userInfo object. The title of the browser action is then set to display the retrieved information. In case of any errors, the title will display the error message.
