Is Youtube Bilingual Subtitles safe?

Medium risk

Youtube Bilingual Subtitles posts its stored NetflixSubs user token into the YouTube page context.

When the extension runs on YouTube, its injected page script requests stored extension values from the content script. The content script reads values including the NetflixSubs user token and user ID from Chrome sync storage and sends them back with window.postMessage using a wildcard target origin.

Shared hosts - 2 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.

Where it sends data

Destinations our analysis observed Youtube Bilingual Subtitles contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
