Claude with full browser control — DOM access, passive API capture, per-site memory, and multi-step workflows. Pick a preset or just ask.No blind execution. Foxhole shows the full code before it runs — you see every DOM query, every script, every action. One click to approve, one to cancel.Claude writes the code, you audit it. Every execute_script call exposes the full payload — readable, reviewable, and cancellable before a single line touches the page.16 tool calls, zero hand-holding. Claude mapped Wikipedia's DOM structure end-to-end and saved the selectors for future sessions — then asked before going further.Works through failures, saves the wins. Claude hit a loop, self-corrected, mapped the full DOM, and banked 5 site specs for every future session. That badge means it never has to rediscover this site again.One visit, permanent memory. Saved specs are injected directly into Claude's system prompt on every return visit — stable selectors, roles, and layout patterns ready to use without re-probing.Site specs pay for themselves. The cache breakdown shows 14,858 tokens served from cache this turn — injected site knowledge reused at a fraction of the cost of reprocessing it fresh every request.
About this extension
A Firefox sidebar where Claude (Anthropic's AI) interacts with web pages on your behalf — clicking elements,
reading content, filling forms, extracting data, and navigating sites through natural conversation.

Key features:
- 63 browser automation tools (DOM, navigation, network, cookies, storage, screenshots)
- Persistent site knowledge — Claude remembers working selectors, API endpoints, and interaction patterns per
domain
- Site profiles — detects whether a site is UI-driven, API-driven, or hybrid
- Prompt injection defense — page content is sanitized before Claude sees it
- Context compression — long conversations stay within token limits
- Two autonomy modes: confirm risky actions (default) or skip confirmations

Requires your own Anthropic API key. All data stays local — the only external call is to Anthropic's API.
