Is ProBlocker - Adblock for YouTube & Web safe?

Low risk

ProBlocker sends YouTube watchtime request details to theproblocker.com when a remote beta mode is enabled.

When its remote beta mode is enabled on YouTube, ProBlocker captures watchtime request parameters along with headers and referrer details and posts them to theproblocker.com APIs. It also exposes the extension's persistent install token to scripts running on YouTube pages via a window message.

Shared hosts - 4 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 ProBlocker 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.
