# Package Identifiers

## Chrome extensions

You can find the identifier in the URL of the extension:

```
https://chromewebstore.google.com/detail/name-of-extension/identifier
```

For example in the case of [Lighthouse](https://chromewebstore.google.com/detail/lighthouse/blipmdconlkpinefehnmjammfjpmpbjk):

```
url: https://chromewebstore.google.com/detail/lighthouse/blipmdconlkpinefehnmjammfjpmpbjk
identifier: blipmdconlkpinefehnmjammfjpmpbjk
```
