Aistos is a military-grade, lightweight (<10MB) session sandbox for Firefox power users. It replaces legacy ad blockers and cookie auto-deleters by orchestrating Firefox's native contextualIdentities and declarativeNetRequest APIs.

---

⚡ Core Architecture

• Ephemeral Burner Workspaces: Launch dynamic sandboxes that instantly vaporize their container, cookies, and indexedDB the moment you close them.
• Native C++ Firewall: Utilizes declarativeNetRequest to block ads and trackers natively in the browser engine without waking up a JavaScript background thread.
• Panic Button Discard: Instantly flush background workspace tabs from memory to freeze tracker execution.
• Memory Ceiling: Aistos operates on event-driven background scripts. It does not maintain global state arrays, keeping memory consumption permanently under 10MB.
• Dynamic Tor Armor & CNAME Uncloaking: Toggles Tor-uplifted C++ preferences exclusively in burners and resolves canonical domain names to drop masked trackers.

🔄 What Aistos Replaces

Aistos is engineered to consolidate a bloated, multi-extension privacy stack into a single, cohesive, zero-framework extension. It directly replaces:

• Temporary Containers: Replaced by Aistos's atomic, event-driven ephemeral Burner Workspaces and automatic context routing.
• Cookie AutoDelete (CAD): Replaced by Aistos's Domain Vaults, auto-detection of persistent logins, and native CAD backup import tooling.
• uBlock Origin / Privacy Badger (Tracker Blocking): Replaced by native C++ declarativeNetRequest (DNR) rule execution, CNAME uncloaking, and recursive URL tracker parameter sanitization.
• CanvasBlocker / Fingerprint Shields: Replaced by context-aware Tor-derived stealth armor (resistFingerprinting) active exclusively inside Burner workspaces, avoiding breakage on regular sites.

Development & Testing

Aistos enforces strict quality and memory budgets via automated CI scripts. To run security and bloat audits locally on your machine:

1. Install development dependencies:

   npm install

2. Run the memory bloat, permission, and leak audits:

   npm run audit:all

3. Lint the codebase:

   npm run lint

4. Build a clean production .xpi package:

   npm run build
