Is UpSeller - Product Importer safe?
UpSeller captures product page HTML and Shopee authentication headers from e-commerce tabs and transmits them to app.upseller.com.
UpSeller is a product-import assistant for online sellers, injecting content scripts into over 15 e-commerce platforms including Amazon, AliExpress, Shopee, and Mercado Libre. When triggered by the UpSeller web app (via external messaging), the extension fetches the full HTML of a product page and uploads it to app.upseller.com/api/crawl/plug-crawl. On Shopee tabs, it also intercepts outgoing request headers—including authentication cookies and tokens—and replays them when making authenticated product data requests on the user's behalf.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 1 hostname
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
