  description

  View profiles and block any Instagram account — even ones that blocked you first

  What it does:
  
  Instagram hides profiles from you when someone blocks you. Instagram Viewer & Blocker bypasses that in both directions:
  - Profile Info — view full profile data for any account regardless of block status;
  - Block — block any account even if they blocked you first.
  
  Features
  
  - Profile lookup — username, full name, bio, external link, profile picture, follower/following/post counts, verified badge, private flag;
  - Works when blocked — anonymous API fallbacks strip session cookies so Instagram's block relationship doesn't apply;
  - One-click block — username auto-fills from the active tab URL; ID resolution happens silently in the background;
  - Self-block prevention — detects and rejects attempts to block your own account;
  - No external server — all requests go directly to Instagram; credentials never leave your browser.
  
  Profile Info shows:
  
      Username (with 🔒 private / ✓ verified badges)
      Full name
      Bio
      External link
      Profile picture
      User ID
      Followers / Following / Posts
  
  Notes
  
      - Must be logged into Instagram in the same browser
      - Cannot block yourself — the extension detects and prevents this
      - DOC_ID in content.js is tied to Instagram's current deploy — if blocking stops working, capture a fresh usePolarisBlockManyMutation request from the Network tab and update the value
      - If you see "Could not fetch profile — try reloading the Instagram tab", do so once
