ImgInn is a Firefox Add-on designed to enhance the Instagram experience by redirecting all Instagram links to imginn.com, an online backup tool for Instagram photos. The add-on utilizes the public API of Instagram, enabling users to save their favorite photos easily. Although initially created for personal use, it has been made available to the public in adherence to Mozilla's guidelines. Users can enjoy a seamless transition from Instagram to the backup tool with just one click, making it a useful tool for anyone looking to preserve their Instagram content.

While ImgInn provides a straightforward solution for Instagram link redirection, users should note that it is not an open-source tool and does not prioritize privacy in the same way as alternatives like Proxigram. To enhance security, it is recommended to use ImgInn alongside privacy-focused tools such as NoScript and Ublock Origin. The add-on is subscription-based and is set to support Proxigram as new instances become available, promising improved reliability for users.
