According to CoinMeta, Claude has now launched two sets of browser features: an independent browser and a Chrome plugin. The independent browser can handle web tasks directly, while the Chrome plugin allows users to operate within a logged-in Chrome environment. The new features also include automatic operations; Claude performs security checks before executing tasks to ensure there are no malicious instructions. The latest red-team tests by Anthropic show that there were no successful prompt injection attacks for Sonnet 5 and Opus 5, with a success rate of 0.3% for Fable 5.
