Is Anybox safe?

Clean risk

Anybox posts active tab URLs to the local Anybox service when its default checkmark feature is enabled.

When tabs activate, update, or browser focus changes, Anybox checks the current page URL by posting it as JSON to http://localhost:6391. The response is used to set the extension badge, and the behavior is enabled by default through the checkmark setting.

Where it sends data
