# Extension ID Lookup

Category: Personal security
Where it runs: Runs locally (nothing you enter is uploaded)

Find out which browser extension an ID belongs to and how risky it is: store links for Chrome, Edge and Firefox, and a plain-language reading of the permissions in its manifest.

## Example input

A "wallet helper" with broad access

```
nkbihfbeogaeaoehlefnkodbefgpgknn
---
{"name": "Wallet Helper", "manifest_version": 3, "permissions": ["storage", "clipboardWrite", "scripting", "tabs"], "host_permissions": ["<all_urls>"]}
```

The ID gives Chrome Web Store and Edge Add-ons links. The manifest is flagged with the wallet-drainer pattern: access to every website plus clipboard writing and script injection, the combination fake wallet extensions use to swap addresses.

## FAQ

### Where do I find an extension’s ID?

In Chrome or Edge open chrome://extensions (edge://extensions), turn on Developer mode and the ID appears under each extension. In Firefox open about:debugging, choose This Firefox, and read the Extension ID. The store URL works too.

### Which permissions are dangerous?

Access to all websites, cookies, history, clipboard reading, debugger, native messaging, management and proxy can expose your accounts and wallets. Ask whether the extension really needs them for what it claims to do.

### Does the tool contact the stores?

No. It only builds links to the store pages and reads the manifest you paste, inside your browser. The store sees the ID only if you open one of the links.
