Is Twitter X Viewer – Anonymous Profile & Tweet Viewer safe?

Low risk

Twitter X Viewer registers browser and extension metadata with its vendor endpoint on install and browser startup.

The extension builds a registration payload with its extension ID, manifest version, browser user agent, platform information, and UI language. It sends that data to its vendor endpoint during install or update and again when the browser starts, then stores the returned UUID locally.
