Cua Driver 0.19.0 puts browser control below the agent, killing the extension dependency.

Released August 6, it binds an exact Chromium tab to its native process and window via Chrome DevTools Protocol, giving page-aware browser actions plus full desktop control in one session, reachable through CLI, MCP, Python, and TypeScript (Cua). Contrast with Claude Code connecting through a Chrome extension that shares browser state, and Codex shipping an in-app browser separate from your profile. Attaching a signed-in profile requires an explicit launch grant rather than a runtime modal, so authorization sits at the policy layer. Given the Brave findings above, that placement matters more than the convenience.
