Is FurimAuto(フリマート) safe?

Clean risk

FurimAuto uploads automation console logs and error page snapshots from Mercari, Rakuma and Yahoo seller pages to its Firebase bucket.

While running bulk listing automation, the extension buffers console output (which can include product names, URLs and API bodies) and, on errors, a full HTML snapshot of the seller page. These are uploaded to the vendor's Firebase Storage under a path that includes the user's LINE display name. A separate page-level hook on jp.mercari.com also caches Mercari draft item API responses and relays them to scripts on the same page.
