Is Amazon Prime Subtitles & Dictionary safe?

Medium risk

Amazon Prime Subtitles & Dictionary adds your email and last watched Amazon URL to its uninstall URL.

When the extension prepares its uninstall page, it builds a URL on appforlanguage.com that includes your stored email, the last Amazon or Prime Video page it recorded, the website name, and subtitle language choices. That URL is opened when you uninstall the extension, sending those values as query parameters to the developer's site.

Shared hosts - 5 hostnames

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.
