Is DuMate Browser Extension safe?

Low risk

DuMate Browser Extension accepts localhost WebSocket commands that attach Chrome Debugger to tabs and inspect pages.

The extension connects to a local WebSocket relay and forwards its JSON commands into the background script, where they can create, attach to, close, and run Chrome DevTools Protocol commands on tabs. It can return tab titles, URLs, frame identifiers, and page inspection results to the local relay, and synthetic clicks on _blank links can also make it open background tabs that join an active relay session.
