Image Download Helper is a Firefox addon designed to enhance the image downloading experience by providing an intuitive context menu. This menu simplifies the process of accessing images, particularly in gallery views where they can be more challenging to find. The addon ensures that users can download images in their original quality, making it a valuable tool for anyone who frequently works with images online.

Additional features include a customizable prefix option, allowing users to add specific prefixes to filenames during downloads, enhancing organization. The addon also includes a Twitter credit feature that automatically detects and appends the username from Twitter posts to downloaded filenames. This functionality not only streamlines the downloading process but also aids in keeping track of image sources.
