This browser extension validates a Trust URI (trust://<domain>!) present in a social media account page, as specified in Internet-Draft Organization Trust Relationship Protocol
https://datatracker.ietf.org/doc/draft-org-trust-relationship-protocol/.
The extension will highlight a Trust URI on a social media account page with an icon, indicating if the Trust URI is validated against the trust.txt file found at the domain specified in the Trust URI. Clicking on the icon will provide an message describing the validation state.
