List of Chromium Command Line Switches
There are lots of command lines which can be used with the Google Chrome browser. Some change behavior of features, others are for debugging or experimenting. This page lists the available switches including their conditions and descriptions. Last automated update occurred on 2013-05-23.
| Condition | Explanation |
|---|---|
| --0 ⊗ | prohibited: never inline matches ↪ |
| --1 ⊗ | The values the kOmniboxInlineHistoryQuickProvider switch may have, as in "--omnibox-inline-history-quick-provider-allowed=1" allowed: if HistoryQuickProvider thinks it appropriate, it can inline ( == current behavior as of 2/2012). ↪ |
| --action-box ⊗ | Enables or disables the "action box" UI in the toolbar. ↪ |
| --allow-cross-origin-auth-prompt ⊗ | Allows third-party content included on a page to prompt for a HTTP basic auth username/password pair. ↪ |
| --allow-file-access ⊗ | On ChromeOS, file:// access is disabled except for certain whitelisted directories. This switch re-enables file:// for testing. ↪ |
| --allow-file-access-from-files ⊗ | By default, file:// URIs cannot read other file:// URIs. This is an override for developers who need the old behavior for testing. ↪ |
| --allow-http-background-page ⊗ | Allows non-https URL for background_page for hosted apps. ↪ |
| --allow-http-screen-capture ⊗ | Allow non-secure origins to use the screen capture API. ↪ |

| --allow-no-sandbox-job ⊗ | Enables the sandboxed processes to run without a job object assigned to them. This flag is required to allow Chrome to run in RemoteApps or Citrix. This flag can reduce the security of the sandboxed processes and allow them to do certain API calls like shut down Windows or access the clipboard. Also we lose the chance to kill some processes until the outer job that owns them finishes. ↪ |
| --allow-outdated-plugins ⊗ | Don't block outdated plugins. ↪ |
| --allow-running-insecure-content ⊗ | By default, an https page cannot run JavaScript, CSS or plug-ins from http URLs. This provides an override to get the old insecure behavior. ↪ |
| --allow-sandbox-debugging ⊗ | Allows debugging of sandboxed processes (see zygote_main_linux.cc). ↪ |
| --allow-scripting-gallery ⊗ | Allows injecting extensions and user scripts on the extensions gallery site. Normally prevented for security reasons, but can be useful for automation testing of the gallery. ↪ |

(So if a.com iframes b.com, the b.com network request will be sent without cookies.) This is expected to break compatibility with many pages for now. Unlike the --site-per-process flag, this allows cross-site iframes, but it blocks all cookies on cross-site requests. ↪ |

Resources for which hidpi is not supported because of software reasons will show up pixelated. ↪ |

Each pattern uses the same syntax as patterns in Chrome extension manifest. The only difference is that * scheme matches all schemes instead of matching only http and https. If the value doesn't start with !, a program will be debugged if manifest URL matches any pattern. If the value starts with !, a program will be debugged if manifest URL does not match any pattern. ↪ |

| --no-first-run ⊗ | Skip First Run tasks, whether or not it's actually the First Run. Overridden by kForceFirstRun. Also drops the First Run beacon so that First Run will not occur in subsequent runs as well. ↪ |
| --no-js-randomness ⊗ | Support a separate switch that enables the v8 playback extension. The extension causes javascript calls to Date.now() and Math.random() to return consistent values, such that subsequent loads of the same page will result in consistent js-generated data and XHR requests.

For details, see: http://www.chromium.org/developers/design-documents/site-isolation Unlike --enable-strict-site-isolation (which allows cross-site iframes), this flag blocks cross-site documents even in iframes, until out-of-process iframe support is available. Cross-site network requests do attach the normal set of cookies, but a renderer process is only allowed to view or modify cookies for its own site (via JavaScript). TODO(irobert): Implement the cross-site document blocking in http://crbug.com/159215. ↪ |

| --trace-startup ⊗ | Causes TRACE_EVENT flags to be recorded from startup. Optionally, can specify the specific trace categories to include (e.g. --trace-startup=base,net) otherwise, all events are recorded. Setting this flag results in the first call to BeginTracing() to receive all trace events since startup. In Chrome, you may find --trace-startup-file and --trace-startup-duration to control the auto-saving of the trace (not supported in the base-only TraceLog component). ↪ |
| --trace-startup-duration ⊗ | Sets the time in seconds until startup tracing ends. If omitted a default of 5 seconds is used. Has no effect without --trace-startup, or if --startup-trace-file=none was supplied. ↪ |
| --trace-startup-file ⊗ | If supplied, sets the file which startup tracing will be stored into, if omitted the default will be used "chrometrace.log" in the current directory. Has no effect unless --trace-startup is also supplied. Example: --trace-startup --trace-startup-file=/tmp/trace_event.log As a special case, can be set to 'none' - this disables automatically saving the result to a file and the first manually recorded trace will then receive all events since startup. ↪ |
| --track-active-visit-time ⊗ | Enables tracking the amount of non-idle time spent viewing pages. ↪ |
| --translate-script-url ⊗ | Overrides the default server used for Google Translate. ↪ |

| --use-fake-device-for-media-stream ⊗ | Use fake device for MediaStream to replace actual camera and microphone. ↪ |
| --use-gl ⊗ | Select which implementation of GL the GPU process should use. Options are: desktop: whatever desktop OpenGL the user has installed (Linux and Mac default). egl: whatever EGL / GLES2 the user has installed (Windows default - actually ANGLE). osmesa: The OSMesa software renderer. ↪ |

| --v ⊗ | Gives the default maximal active V-logging level; 0 is the default. Normally positive values are used for V-logging levels. ↪ |
| --validate-crx ⊗ | Examines a .crx for validity and prints the result. ↪ |
| --variations-server-url ⊗ | Specifies a custom URL for the server which reports variation data to the client. Specifying this switch enables the Variations service on unofficial builds. See variations_service.cc. ↪ |

How to use a command line switch?
