Is Tab Manager for Chrome™ safe?

Medium risk

Tab Manager for Chrome exposes current-window tab titles to pages when its overlay is opened.

The extension injects its tab-manager UI into every website and mounts it in an open shadow root. When the overlay is opened, it requests all tabs in the current window and renders their titles and favicons where scripts on the underlying page can read them.
