Instagram does not provide a native 'Download' button for photos in posts. This extension solves that by injecting a download button into the post UI.

1. User visits an Instagram post page (https://www.instagram.com/p/*). 2. The extension's content script detects the post elements using MutationObserver. 3. If the post contains an image (not a video), a 'Download' button is injected next to the bookmark icon. 4. When clicked, the script extracts the image source URL and sends it to the background service worker. 5. The background service worker triggers a browser download of the image.

目标用户: Instagram users who want to save photos from their feed or profiles to their local device

The extension relies on Instagram's internal CSS class names (e.g., 'x1ypdohk', '_aatb') which are subject to change without notice, potentially breaking functionality. The analysis is based on static code review and does not test runtime behavior against live Instagram pages.

付费分析

未识别到付费功能

The extension is a simple utility that adds a 'Download' button to Instagram image posts. There is no code related to subscriptions, payments, licensing, or premium features. The keyword 'pro' found in the static analysis was a false positive from the _metadata/verified_contents.json file (Chrome Web Store verification metadata), not actual extension logic.

登录理由: The extension does not implement any login mechanism, nor does it redirect to a login page. It operates by injecting scripts into Instagram post pages (https://www.instagram.com/p/*). While the user must be logged into Instagram to view private or restricted posts, the extension itself does not require or handle authentication. The core workflow (adding a download button and fetching image URLs) functions without any extension-side login.
