Is Advanced Downloader for Instagram™ safe?

Medium risk

Advanced Downloader for Instagram sends search queries and result URLs to mtusgate.de and rewrites matched links.

The extension runs a helper script on every website, including search-result pages, and reads the search query plus result-link URLs from the page. It posts that data to mtusgate.de for matching, then replaces matching result links with redirect URLs that route clicks through mtusrede.de.

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.
