Changelog

  description

  QA Settings injects Chrome DevTools Protocol (CDP) overrides into tabs you
  choose — without opening DevTools. Switch timezone/locale, throttle the
  network, force dark mode, auto-grant permissions, and more, all from a single
  toolbar toggle.
  
  Use cases
  - Verify timezone/locale-sensitive UI across UTC, Europe/London, Asia/Tokyo…
  - Reproduce slow-network, offline, or low-CPU bugs without external tools
  - Test responsive layouts, dark mode, color-blindness filters
  - Auto-accept camera/mic/geolocation prompts in QA flows
  - Reproduce first-visit state by bulk-clearing storage + cookies (domain-wide)
  
  Features
  
  CLIENT — signals the browser tells the site about the user
  - Timezone override (100+ IANA presets + free text)
  - Locale override (navigator.language + Intl.* formats)
  - Geolocation override (lat/lng/accuracy + 30 city presets + "use current")
  - User-Agent override (preset UAs + custom string)
  
  NETWORK
  - Network throttling (Offline/Slow3G/Fast3G/Slow4G/Fast4G/WiFi + custom)
  - Disable HTTP cache
  - Block URL patterns (simulate missing GA/ads/specific APIs)
  - Inject request headers (auth tokens, A/B flags)
  - Set cookies — DevTools Application panel fields exactly
    (name/value/domain/path/expires/httpOnly/secure/sameSite)
  
  RENDERING
  - Color scheme: force prefers-color-scheme light/dark
  - Device emulation: viewport/DPR/mobile flag + 9 device presets
  - CPU throttling: slowdown multiplier
  - Vision deficiency: color-blind/blur filters for accessibility QA
  
  PERMISSIONS & STATE
  - Auto-grant site permissions (camera/mic/notifications/geolocation/…)
  - Force navigator.idleDetector state (active/idle/locked)
  - Clear origin storage + domain-tree cookies (reproduce first-visit / logout)
  
  GENERAL
  - Domain scope — apply only to tabs matching glob/regex patterns
  - Presets — save feature combos ("Payment QA", "Mobile offline", …) + one-click switch
  - Import/Export settings as JSON — share across team
  
  Privacy
  All settings stay in chrome.storage.local on your device. No network
  requests, no telemetry, no analytics.
  
  Permissions
  - debugger — required to send CDP Emulation/Network/Browser/Storage commands
  - storage — persist your toggle state locally
  - tabs — detect tab navigation to re-apply overrides
  - cookies — domain-tree cookie cleanup (e.g. logout a whole site)
  - host_permissions <all_urls> — CDP attach needs a host target; you choose
    which tabs via Domain Scope
  
  Localization
  UI available in 10 languages: English, 한국어, 中文, Español, 日本語,
  Deutsch, Français, Português, Русский. Auto-detects browser locale by default.
