Is JavaScript Errors Notifier safe?

Low risk

JavaScript Errors Notifier lets webpages request extension storage option values through its all-sites message bridge.

JavaScript Errors Notifier runs content scripts on all sites and relays page messages that ask for named extension options. The background script returns the requested value from Chrome local storage, so a page can receive settings such as domain include lists and per-site icon or popup preferences.
