This extension provides real-time weather information for the user's current location. The code uses the browser's built-in geolocation API to retrieve the user's latitude and longitude, and then calls an external weather API to fetch the weather data. The extension displays the location name, temperature, weather conditions, and a weather icon in a visually appealing format. With this extension, users will never have to guess what the weather is like outside, as they'll have the most up-to-date information right at their fingertips.
