Clone the repository from GitHub, open Chrome and go to chrome://extensions, enable Developer Mode, click "Load unpacked" and select the FSB folder. The extension icon will appear in your toolbar.

We recommend xAI Grok 4.1 Fast for the best balance of speed and accuracy. It has a 2M token context window and costs $0.20/$0.50 per million tokens. For a free option, try Gemini 2.0 Flash (experimental). For maximum quality, use Claude Opus 4.1 or Grok 4.1. You can also use OpenRouter to access 200+ models through a single API key.

FSB itself is free. You only pay for the AI provider API usage. A typical automation task uses a few thousand tokens, costing fractions of a cent with budget models. Gemini 2.0 Flash is completely free (experimental). The dashboard tracks your spending in real time.

FSB supports Chrome 88+ and all Chromium-based browsers including Microsoft Edge, Brave, Opera, and Vivaldi. Firefox support is planned for a future release.

Yes. API keys are encrypted using AES-GCM before being stored in Chrome's local storage. They are only decrypted in-memory when making API calls. Keys are never logged, exported, or transmitted to any server other than your chosen AI provider.

FSB has built-in stuck detection and recovery. If it detects it is repeating actions or not making progress, it will try alternative strategies. If all recovery attempts fail, it stops gracefully and reports what happened in the chat. You can always stop automation manually at any time.

FSB can detect CAPTCHAs and includes 2Captcha integration supporting reCAPTCHA v2, hCaptcha, and Cloudflare Turnstile. Enable it in Options with your 2Captcha API key. Slider CAPTCHAs are handled with dedicated CDP drag tools. If automatic solving is not configured, FSB pauses so you can solve manually and then resume.

FSB includes action validation and safety checks. It only performs actions on the current tab and only when explicitly instructed. All code is open source and auditable. That said, use caution with tasks involving sensitive accounts or financial transactions -- always review what FSB is doing.

Open an issue on the GitHub Issues page. Include the website URL, your task description, and any error messages from the FSB chat or browser console. Session logs from the Debug tab in Options can also help.

FSB is open source under the BSL 1.1 License. Fork the repository, make your changes, and submit a pull request. Check the CLAUDE.md file for architecture details and coding guidelines. Contributions of all kinds are welcome -- code, documentation, bug reports, and feature suggestions.

Background Agents let you schedule automated tasks to run on a recurring basis -- every N minutes, daily at a specific time, or as a one-shot. FSB can also record your automation workflows and replay them without AI calls, dramatically reducing costs. Agent run history, success rates, and cost savings are tracked in the dashboard.

MCP (Model Context Protocol) lets you control FSB from AI coding tools like Claude Code or Cursor. Install the fsb-mcp-server npm package, add it to your MCP client configuration, and you can automate browsers directly from your IDE. FSB exposes 50+ browser actions as MCP tools.

Yes. The Remote Dashboard at full-selfbrowsing.com lets you pair with your FSB extension via QR code, then send tasks, view a live DOM preview of the browser, and monitor agent runs -- all from any device with a web browser.

FSB has a local memory system with three layers: semantic memory (site navigation patterns), episodic memory (past action sequences), and procedural memory (successful workflows). This data stays on your device and helps FSB navigate familiar sites faster and avoid repeating mistakes. Memory auto-consolidates after enough sessions.

Yes. FSB has full Excalidraw mastery and a Universal Canvas Vision system that intercepts canvas draw calls to understand what is on screen. It supports text entry, drawing primitives, styling, connectors, alignment, and export across 12+ canvas-based applications including Excalidraw, Photopea, and Miro.
