Extension Usage Instructions

Content Credentials adds machine-readable and verifiable manifests to online assets to track the origin and history of online assets using the C2PA standard.
This extension automatically checks for manifests attached to images on the pages you are browsing. If an image has a manifest, the extension will validate it and make the results available via a click on the Content Credentials “CR” pin icon.

Features:
- Right click on an image and select `Verify Content Credentials` to trigger the verification.
- Or toggle on or off the automatic detection of images with manifests.
- Validates manifest when present and adds a "CR" pin to the image.
- Hovering the "CR" pin displays a summary of the manifest in a pop up
