- Websites can detect DevTools using timing attacks, console API monitoring, debugger traps, resize detection, and source map requests.
- Existing solutions like scripts, extensions, and gists are often bypassed by modern detection techniques.
- The only reliable method is to use a patched browser like LibreWolf that fundamentally breaks or removes detection vectors.
- Key LibreWolf configuration: set `librewolf.console.logging_disabled` to true to disable console API logging.
- Set `librewolf.debugger.force_detach` to true to prevent debugger attachment and debugger keyword traps.
- Set `devtools.toolbox.host` to `window` to open DevTools in a separate window, avoiding resize detection.
- Set `devtools.source-map.client-service.enabled` to false to prevent source map requests that flag detection.
- Optional: enable `webgl.disabled` to false and `privacy.resistFingerprinting` to false to avoid fingerprinting issues on some sites.
