Instagram Viewer & Blocker

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
