Is Fast save and repost for Instagram safe?

Fast save and repost for Instagram collects Instagram session cookies and auth headers, and sends Instagram link URLs to third-party spector.cx domains on user interaction.

The extension's background service worker reads all Instagram session cookies via chrome.cookies.getAll and captures authentication headers (x-ig-www-claim, x-asbd-id, x-instagram-ajax) from intercepted Instagram network requests, storing them locally for use in automated API calls. Content scripts injected into every page detect Instagram links and, when a user clicks a link overlay, open a new tab to one of three spector.cx-family domains (spector.cx, spector.team, or spector.ac) with the Instagram URL appended as a query parameter.
