⚙️🕵️♂️ Hidden/Secret Browser Menus & Settings (Updated Jan 2026)
January 21, 2026 · View on GitHub
Secret/hidden internal pages exist across Chromium-based browsers and are accessed with chrome:// (Chrome/Brave) or edge:// (Microsoft Edge). These pages expose diagnostics, experiments, performance tools, and troubleshooting utilities that aren't always visible in standard settings.
Authoritative Lists:
- Chrome/Brave:
chrome://chrome-urls(alias:chrome://about)- Edge:
edge://edge-urls
Legend / Notes
- [Stable]: Generally available in current desktop builds.
- [Legacy]: Still present, but tied to features being deprecated.
- [Build/Flag-gated]: May require a specific OS/build/channel or a feature flag; may be hidden by enterprise policy.
- [Deprecated]: Removed or non-functional in current Chrome; keep for historical context with a pointer to replacements.
⚠️ Enterprise: Admin policies can hide or disable some internal URLs.
🧭 Per-version variability: Items can move, be renamed, or vanish between releases. Always verify on your installed version viachrome://chrome-urls/edge://edge-urls.

Notes for Edge & Brave
- Microsoft Edge:
edge://edge-urlslists internal pages. Manyedge://…pages mirror Chrome’s (flags,gpu,net-export, etc.). Some legacy pages likeedge://net-internalsmay still exist but are in the same deprecation path as Chrome’s. - Brave: Use
brave://chrome-urls. The list often displayschrome://links but they map to Brave’s internals.
Chrome Apps Deprecation (Context for “Legacy” rows)
Chrome Apps are being phased out: deprecation phases began in 2025 with end-of-life in 2028 (on managed ChromeOS timelines). Keep chrome://apps / chrome://app-service-internals rows labeled [Legacy]; they’re largely irrelevant off-ChromeOS and will diminish over time.
Handy Dev Workflows
- Network debugging (modern):
- Live capture in DevTools → Network
- Long-running or background capture:
chrome://net-export→ save NetLog → open in NetLog Viewer.
- Performance investigations:
chrome://settings/performanceto tune Memory Saver modes and set always-active site exceptions.chrome://tracing(when available) for low-level traces; or use DevTools Performance panel.
