Causes the browser to launch directly in incognito mode.
|--disable-hang-monitor ||Suppresses hang monitor dialogs in renderer processes. |
|--disable-metrics ||Completely disables UMA metrics system. |
|--disable-metrics-reporting ||Disables only the sending of metrics reports. In contrast to |
kDisableMetrics, this executes all the code that a normal client would use
for reporting, except the report is dropped rather than sent to the server.
This is useful for finding issues in the metrics code during UI and
|--assert-test ||Causes the browser process to throw an assertion on startup. |
|--renderer-assert-test ||Causes the renderer process to throw an assertion on launch. |
|--crash-test ||Causes the browser process to crash on startup. |

for running the plugin process through purify or quantify.
|--channel ||The value of this switch tells the child process which |
IPC channel the browser expects to use to communicate with it.
|--testing-channel ||The value of this switch tells the app to listen for and broadcast |
testing-related messages on IPC channel with the given ID.

in newly-opened tabs. We need this for testing purposes so
that the UI tests don't depend on what comes up for http://google.com.
|--start-renderers-manually ||When this switch is present, the browser will throw up a dialog box |
asking the user to start a renderer process independently rather
than launching the renderer itself. (This is useful for debugging.)

|--renderer-path ||Path to the exe to run for the renderer subprocess |
|--plugin ||Causes the process to run as plugin host |
|--single-process ||Runs the renderer and plugins in the same process as the browser |
|--process-per-tab ||Runs each set of script-connected tabs (i.e., a BrowsingInstance) in its own |
renderer process. We default to using a renderer process for each
site instance (i.e., group of pages from the same registered domain with
script connections to each other).
|--process-per-site ||Runs a single process for each site (i.e., group of pages from the same |
registered domain) the user visits. We default to using a renderer process
for each site instance (i.e., group of pages from the same registered
domain with script connections to each other).
|--in-process-plugins ||Runs plugins inside the renderer process |
|--no-sandbox ||Runs the renderer outside the sandbox. |

for all of its state.
|--app ||Specifies that the associated value should be launched in "application" mode. |
|--upload-file ||Specifies the file that should be uploaded to the provided application. This |
switch is expected to be used with --app option.
|--dom-automation ||Specifies if the dom_automation_controller_ needs to be bound in the |
renderer. This binding happens on per-frame basis and hence can potentially
be a performance bottleneck. One should only enable it when automating
dom based tests.
|--plugin-path ||Tells the plugin process the path of the plugin to load |
|--js-flags ||Specifies the flags passed to JS engine |
|--geoid ||The GeoID we should use. This is normally obtained from the operating system |

|--lang ||The language file that we want to try to open. Of the form |
language[-country] where language is the 2 letter code from ISO-639.
|--debug-children ||Will add kDebugOnStart to every child processes. If a value is passed, it |
will be used as a filter to determine if the child process should have the
kDebugOnStart flag passed on or not.
|--wait-for-debugger-children ||Will add kWaitForDebugger to every child processes. If a value is passed, it |
will be used as a filter to determine if the child process should have the
kWaitForDebugger flag passed on or not.
|--log-filter-prefix ||Will filter log messages to show only the messages that are prefixed |
with the specified value
|--enable-logging ||Force logging to be enabled. Logging is disabled by default in release |
|--disable-logging ||Force logging to be disabled. Logging is enabled by default in debug |
|--log-level ||Sets the minimum log level. Valid values are from 0 to 3: |
INFO = 0, WARNING = 1, LOG_ERROR = 2, LOG_FATAL = 3.
|--dump-histograms-on-exit ||Dump any accumualted histograms to the log when browser terminates (requires |
logging to be enabled to really do anything). Used by developers and test
|--remote-shell-port ||enable remote debug / automation shell on the specified port |
|--uninstall ||Runs un-installation steps that were done by chrome first-run. |
|--omnibox-popup-count ||Number of entries to show in the omnibox popup. |
| || |
|--automation-channel ||The value of this switch tells the app to listen for and broadcast |
automation-related messages on IPC channel with the given ID.
|--restore-last-session ||Indicates the last session should be restored on startup. This overrides |
the preferences value and is primarily intended for testing.
|Chrome supports a playback and record mode. Record mode saves *everything* |
to the cache. Playback mode reads data exclusively from the cache. This
allows us to record a session into the cache and then replay it at will.
|--no-events ||Don't record/playback events when using record & playback. |
|Make Windows happy by allowing it to show "Enable access to this program" |
checkbox in Add/Remove Programs->Set Program Access and Defaults. This
only shows an error box because the only way to hide Chrome is by
|--make-default-browser ||Make Chrome default browser |
|--proxy-server ||Use a specified proxy server, overrides system settings. This switch only |
affects HTTP and HTTPS requests.
|Chrome will support prefetching of DNS information. Until this becomes |
the default, we'll provide a command line switch.
|--debug-print ||Enables support to debug printing subsystem. |
|--allow-all-activex ||Allow initialization of all activex controls. This is only to help website |
developers test their controls to see if they are compatible in Chrome.
Note there's a duplicate value in activex_shared.cc (to avoid
dependency on chrome module). Please change both locations at the same time.
|--disable-dev-tools ||Browser flag to disable the web inspector for all renderers. |
|--always-enable-dev-tools ||Enable web inspector for all windows, even if they're part of the browser. |
Allows us to use our dev tools to debug browser windows itself.
|--tab-count-to-load-on-session-restore ||Used to set the value of SessionRestore::num_tabs_to_load_. See |
session_restore.h for details.
const wchar_t kTabCountToLoadOnSessionRestore =
|--memory-profile ||Enable dynamic loading of the Memory Profiler DLL, which will trace |
all memory allocations during the run.
|--memory-model ||Configure Chrome's memory model. |
Does chrome really need multiple memory models? No. But we get a lot
of concerns from individuals about how the changes work on *their*
system, and we need to be able to experiment with a few choices.
|--enable-file-cookies ||By default, cookies are not allowed on file://. They are needed in for |
testing, for example page cycler and layout tests. See bug 1157243.
|--start-maximized ||Start the browser maximized, regardless of any previous settings. |
TODO(pjohnson): Remove this once bug 1137420 is fixed. We are using this
as a workaround for not being able to use moveTo and resizeTo on a
|--enable-watchdog ||Spawn threads to watch for excessive delays in specified message loops. |

whether or not it's actually the first run.

count, object signalling count, etc.
|--import ||Perform importing from another browser. The value associated with this |
setting encodes the target browser and what items to import.
|--silent-dump-on-dcheck ||Change the DCHECKS to dump memory and continue instead of crashing. |
This is valid only in Release mode when --enable-dcheck is specified.
|--disable-prompt-on-repost ||Normally when the user attempts to navigate to a page that was the result of |
a post we prompt to make sure they want to. This switch may be used to
disable that check. This switch is used during automated testing.
|--disable-popup-blocking ||Disable pop-up blocking. |
|--disable-java ||Prevent Java from running. |
|--disable-plugins ||Prevent plugins from running. |
|--disable-images ||Prevent images from loading. |
