The Image Downloader by Mr. Rainbow

This extension is aimed at simplifying the process of downloading images from a list of URLs. It is designed to work seamlessly in both Firefox and Chrome browsers, making it versatile for a wide range of users.

The browser type is detected to accommodate differences between Firefox and Chrome, ensuring that the extension functions correctly in both environments. It responds to events such as the extension being installed and messages received from the extension's content script.

One of the primary functions of this extension is to download images specified in a list of image URLs. When a message with the action 'downloadImages' is received, it splits the list of URLs, fetches each image, and initiates the download process using the respective browser's download API. Users can customize the filename of the downloaded images to suit their preferences.

Additionally, this extension incorporates an event page that provides a user interface for managing downloaded items. It displays the most recently downloaded item, allowing users to view or open it using the associated application. Furthermore, users can choose to remove the downloaded item from both their disk and the download history, providing a clean and efficient way to manage downloaded content.

Overall, the script enhances the functionality of the browser extension, making it easier for users to download images from URLs while maintaining compatibility with popular browsers like Firefox and Chrome.
