QA Settings

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 include/exclude glob or 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.
