Is NeoCertified Messaging (MED1) safe?

Low risk

NeoCertified Messaging exposes a Gmail page-world bridge that can perform same-origin XHRs and return responses.

On Gmail pages, the extension injects a page-world message bridge that accepts a MessagePort using a bundled module ID. Messages on that port can create XMLHttpRequest objects, set headers, send requests, and receive status, headers, response URLs, and response text back through the port.
