Is Fulfil.IO safe?

Clean risk

Fulfil.IO exposes its extension ID and version to Fulfil web pages through a DOM marker.

On fulfil.io and fulfil.app pages, the content script reads the extension manifest version and runtime ID, then appends a fulfil-ext element to the page. Scripts on those Fulfil pages can read those attributes; the stored claim does not identify a network endpoint or other browsing data collection.
