Security, Prompt Injection & “Lethal Trifecta”

  • Central concern: giving an LLM control of a real browser combines private data access, exposure to untrusted content, and the ability to exfiltrate or act—seen as an almost ideal attack surface.
  • Anthropic’s own number (≈11% attack success after mitigations) is widely viewed as unacceptable, especially given unbounded attempts; comparisons are made to leaving a credit card with PIN in public.
  • Prompt injection via hidden or invisible page text is a dominant fear: draining crypto, changing account details, sending sensitive data, or silently altering email workflows.
  • Many argue “guardrail prompts” and heuristic filters are fundamentally brittle; some liken this to running curl | bash on every page visited.
  • A minority think risks are just another security arms race (like OS zero-days) and can be progressively managed with confirmations, tool whitelists, and better architectures (dual-LLM, controllers, typed taint tracking).

Privacy & Governance

  • Strong worry that browsing contents and history effectively flow to Anthropic, with policy-violating content potentially logged indefinitely.
  • Enterprise use is seen as especially fraught: unclear data governance, auditability, and liability if the agent leaks or misuses sensitive data.

Practicality, UX, and Ethics

  • Many refuse to install it on their main browser; suggestions include separate profiles, VMs, or a dedicated sandboxed browser.
  • Some see clear utility (email triage, language help, QA flows, lead research, form-filling), but others question whether per-action confirmations defeat the point of automation.
  • Strong cultural backlash against AI-written one‑to‑one communication; some posters treat it as socially deceptive and corrosive to “having a society” of real human interaction.

Technical Limits of Browser Agents

  • Multiple commenters report current agents quickly “lose the thread” in real browsing: context rot, DOM churn, popups, and long flows cause stalls or premature “all done” states.
  • Debate over representations: raw DOM + screenshots are huge and noisy; alternatives include compacted DOM, accessibility trees, or explicit APIs (MCP/WebMCP).
  • Some advocate record‑and‑replay plans with minimal LLM calls for robustness over hours-long tasks.

Launch, Webpage Issues & Competitive Context

  • The rollout is very small (≈1,000 Max users) and heavily caveated as a risky research preview; some see that as responsible, others as legal cover while using users as dangerous QA.
  • The announcement page initially shipped with missing text, prompting jokes that it was “vibe-coded” by an AI and emblematic of rushing.
  • Broader strategic threads: Chrome dominance and Gemini integration may disadvantage Anthropic, but agentic browsing could also undercut Google’s ad model if bots become the primary “users” of the web.
