Why “entire” is technically difficult
Messenger does not place every historical message on the page at once. The browser loads older content while scrolling, and some content can leave the active structure.
Use Auto Scan deliberately
Keep the conversation tab active, watch progress and avoid interacting with the page while the scan is loading older history.
Divide large exports
Part-by-part files are easier on browser memory and make it simpler to retry a failed section without starting the full job again.
Know what complete means
A complete export can only include content the platform still exposes to the account and browser. Deleted, expired or inaccessible items cannot be recreated by an extension.
