## Description

LastModifiedInfo is a Chrome extension designed to notify users about the last modified date and time of any webpage. It retrieves the date information directly from the HTTP protocol sent by the web server, providing a more accurate update status than unreliable browser or server-set timestamps. Users can choose between two notification types: a JavaScript alert or an HTML popup. The HTML popup is customizable in design and automatically fades out without requiring user interaction.

The extension addresses common issues where the lastModified date may be inaccurate due to server or browser behaviors. For advanced customization, users can adjust the popup's CSS properties, including the z-index, to ensure visibility over webpage elements. This makes LastModifiedInfo a practical tool for web developers, content managers, and users wanting to track webpage updates efficiently.
