ContainSite 作成者: salmutt

Every website you visit is automatically placed in its own isolated container with a unique, deterministic device fingerprint. Sites cannot share sessions, cookies, or correlate you through browser fingerprinting.

Features:
- Automatic per-site containers — no configuration needed
- 20 spoofed fingerprint vectors: Canvas, WebGL, AudioContext, Navigator, Screen, Timezone, WebRTC, Fonts, Font API, ClientRects, Plugins, Battery, Connection, HTTP Headers, Speech Synthesis, matchMedia, Performance Timing, Storage Estimate, Gamepad, import/export
- HTTP header spoofing — User-Agent, Accept-Language, and Client Hints per container
- Cloudflare-safe mode — per-container shield toggle that disables vectors causing bot detection (UA, platform, WebGL, screen) while keeping undetectable vectors active (canvas, audio, fonts, timezone)
- Auth-aware — login redirects stay in the originating container
- Preserve original tab — cross-domain link clicks open a new container tab, keeping your current page open
- Options page to toggle individual vectors, whitelist domains, auto-prune inactive containers, and manage containers
- Per-container vector overrides — fine-tune spoofing for individual sites
- Import/export all settings

Works alongside Firefox Multi-Account Containers. No external dependencies. Zero data collection.
