Just click the image or video you want to download, and its url will be copied to your clipboard. You can download or open it too. Works for stories, profiles, slideshows, IGTV, DMs, and the feed. This extension will always give you the highest resolution version of an image or video — this is often larger than what Instagram displays. This is an open-source project on GitHub: https://github.com/ehmorris/High-Resolution-Downloader-For-Instagram
