Description

Content Credentials add machine-readable and verifiable manifests to online assets to track the origin and history of online assets using the C2PA standard. When right-clicking on an image (jpg), video (mpeg) or audio file (wav or mp3) and selecting the `Verify Content Credentials` menu, this extension checks for manifests attached to the assets. If an asset 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, video or audio clip and select `Verify Content Credentials` to trigger the verification. - Or toggle on or off the automatic detection of assets with manifests. - Validates manifest when present and adds a "CR" pin to the assets. - Hovering the "CR" pin displays a summary of the manifest in a pop up. - Supports recovering content credentials based on Digimarc digital watermarks (durable content credentials).

When I run `Verify Content Credentials`, it changes the id attribute of the img element in HTML. This breaks the layout on some web pages and causes images to appear very large. It also causes problems in web applications that depend on the id attribute value. Until this bug is fixed, I will not use this extension. Developers, YOU MUST NEVER REWRITE THE ID ATTRIBUTE.

I am not sure when this bug started, but when enabled this extension, videos crash on X.com.
