Is Mostra safe?

Clean risk

Automatically redirects supported websites to their Catalan versions when available.

This extension detects whether the page you are visiting has a Catalan version and redirects you to it automatically. The store description states that it runs only inside the browser and does not collect, store, or send personal or browsing data.

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.
