Claude Now Has Two Browser Modes: Open Webpages Independently or Directly Take Over Chrome

Beating AI News Flash: Anthropic has simultaneously upgraded Claude with two browser capabilities. The desktop version of Claude Cowork now comes with an independent browser, which opens directly in the sidebar when handling webpage tasks. Claude can browse webpages, click, input, and fill out forms on its own, no longer requiring the installation of Chrome plugins. Meanwhile, Claude in Chrome has completed testing and is officially available to all paid plans. The biggest difference between the two modes lies in login states. Cowork uses Claude's own browser, separated from the user's regular browser, and by default cannot access your tabs, bookmarks, or passwords. Users can manually import login information for specific websites. On the other hand, Claude in Chrome directly operates within your already-open and logged-in Chrome browser, making it more suitable for handling emails, CRM systems, or webpages currently being edited. The Chrome version now also supports automated operations. Previously, Claude required user approval for almost every step it executed. Now, it scans webpages for malicious commands and checks whether the intended actions align with the original task. If the safety checks pass, it can proceed autonomously. In Anthropic's latest red team testing, Sonnet 5 and Opus 5 showed no successful prompt injection attacks, while Fable 5 had a success rate of 0.3%. However, the company acknowledges that such risks cannot be entirely eliminated. [Original Link]
