Is Custom UserAgent String safe?

Clean risk

This extension lets you set custom browser user-agent strings for specific websites or URLs.

It provides an options page where you can add, disable, or delete user-agent rules, with more than 100 sample user-agent strings available. A toolbar popup includes an ON/OFF switch, and the options page can convert URL entries to domain-based rules.

What this publisher told the store about itself, and the other listings that told it the same thing.

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.
