--/prefetch:1[1] ⊗
/prefetch:# arguments to use when launching various process types. It has been observed that when file reads are consistent for 3 process launches with the same /prefetch:# argument, the Windows prefetcher starts issuing reads in batch at process launch. Because reads depend on the process type, the prefetcher wouldn't be able to observe consistent reads if no /prefetch:# arguments were used. Note that the browser process has no /prefetch:# argument; as such all other processes must have one in order to avoid polluting its profile. Note: # must always be in [1, 8]; otherwise it is ignored by the Windows prefetcher. ↪

--/prefetch:4[1] ⊗
No description ↪

--/prefetch:5[1] ⊗
/prefetch:# arguments for the browser process launched in background mode and for the watcher process. Use profiles 5, 6 and 7 as documented on kPrefetchArgument* in content_switches.cc. ↪

--/prefetch:8[1] ⊗
/prefetch:# argument shared by all process types that don't have their own. It is likely that the prefetcher won't work for these process types as it won't be able to observe consistent file reads across launches. However, having a valid prefetch argument for these process types is required to prevent them from interfering with the prefetch profile of the browser process. ↪

--accept-lang ⊗
----------------------------------------------------------------------------- Can't find the switch you are looking for? Try looking in: ash/constants/ash_switches.cc base/base_switches.cc etc. When commenting your switch, please use the same voice as surrounding comments. Imagine "This switch..." at the beginning of the phrase, and it'll all work out. ----------------------------------------------------------------------------- Specifies Accept-Language to send to servers and expose to JavaScript via the navigator.language DOM property. language[-country] where language is the 2 letter code from ISO-639. ↪

--accept-resource-provider ⊗

--additional-trust-token-key-commitments ⊗
Manually sets additional Trust Tokens key commitments in the network service to the given value, which should be a JSON dictionary satisfying the requirements of TrustTokenKeyCommitmentParser::ParseMultipleIssuers. These keys are available in addition to keys provided by the most recent call to TrustTokenKeyCommitments::Set. For issuers with keys provided through both the command line and TrustTokenKeyCommitments::Set, the keys provided through the command line take precedence. This is because someone testing manually might want to pass additional keys via the command line to a real Chrome release with the component updater enabled, and it would be surprising if the manually-passed keys were overwritten some time after startup when the component updater runs. ↪

--allow-profiles-outside-user-dir ⊗
Allows profiles to be created outside of the user data dir. TODO(https://crbug.com/1060366): Various places in Chrome assume that all profiles are within the user data dir. Some tests need to violate that assumption. The switch should be removed after this workaround is no longer needed. ↪

--allow-ra-in-dev-mode ⊗
Allows remote attestation (RA) in dev mode for testing purpose. Usually RA is disabled in dev mode because it will always fail. However, there are cases in testing where we do want to go through the permission flow even in dev mode. This can be enabled by this flag. ↪

--arc-start-mode ⊗
Defines how to start ARC. This can take one of the following values: - always-start automatically start with Play Store UI support. - always-start-with-no-play-store automatically start without Play Store UI. If it is not set, then ARC is started in default mode. ↪

--arc-tos-host-for-tests ⊗
Sets ARC Terms Of Service hostname url for testing. ↪

--arcvm-ureadahead-mode ⊗

--audio-process-high-priority[1] ⊗
Use high priority for the audio process. ↪

--audio-service-quit-timeout-ms ⊗
Set a timeout (in milliseconds) for the audio service to quit if there are no client connections to it. If the value is negative the service never quits. ↪

--aue-reached-for-update-required-test ⊗
If this switch is passed, the device policy DeviceMinimumVersion assumes that the device has reached Auto Update Expiration. This is useful for testing the policy behaviour on the DUT. ↪

--aura-legacy-power-button ⊗

The switch value only needs to be substring of the capture source name, i.e. "display" would match "Built-in display" and "External display", whichever comes first. ↪

--auto-select-tab-capture-source-by-title ⊗
This flag makes Chrome auto-select a tab with the provided title when the media-picker should otherwise be displayed to the user. This switch is very similar to kAutoSelectDesktopCaptureSource, but limits selection to tabs. This solves the issue of kAutoSelectDesktopCaptureSource being liable to accidentally capturing the Chromium window instead of the tab, as both have the same title if the tab is focused. ↪

If this flag is set, it indicates that this device is a "Cellular First" device. Cellular First devices use cellular telephone data networks as their primary means of connecting to the internet. Setting this flag has two consequences: 1. Cellular data roaming will be enabled by default. 2. UpdateEngine will be instructed to allow auto-updating over cellular data connections. ↪

--change-stack-guard-on-fork ⊗
After a zygote forks a new process, change the stack canary. This switch is useful so not all forked processes use the same canary (a secret value), which can be vulnerable to information leaks and brute force attacks. See https://crbug.com/1206626.

The switch value must be a comma-separated list of Base64-encoded SHA-256 SPKI Fingerprints (RFC 7469, Section 2.4). This switch has no effect unless --user-data-dir (as defined by the content embedder) is also present. ↪
--ignore-google-port-numbers ⊗ | When set, this will ignore the PortPermission passed in the google_util.h methods and ignore the port numbers. This makes it easier to run tests for features that use these methods (directly or indirectly) with the EmbeddedTestServer, which is more representative of production. ↪
--ignore-gpu-blocklist ⊗ | Ignores GPU blocklist. ↪
--ignore-urlfetcher-cert-requests ⊗ | Causes net::URLFetchers to ignore requests for SSL client certificates, causing them to attempt an unauthenticated SSL/TLS session. This is intended for use when testing various service URLs (eg: kPromoServerURL, kSbURLPrefix, kSyncServiceURL, etc). ↪
--ignore-user-profile-mapping-for-tests ⊗ | If true, profile selection in UserManager will always return active user's profile. TODO(nkostlyev): http://crbug.com/364604 - Get rid of this switch after we turn on multi-profile feature on ChromeOS. ↪
--ime[6] ⊗ | No description ↪
--in-process-broker ⊗ | Creates the service broker inside of this process. Only one process should host the service broker. ↪
--in-process-gpu ⊗ | Run the GPU process as a thread in the browser process. ↪
--incognito ⊗ | Forces Incognito mode even if user data directory is specified using the --user-data-dir switch. ↪
--init-done-notifier ⊗ | The handle of an event to signal when the initialization of the main process is complete (including loading all DLL's). This is used by the integration test to check that forbidden modules aren't loaded outside the sandbox. If this is set, the main process will signal the event and then wait for the integration test to signal it as well before continuing. Ignored in official builds. ↪
--initial-preferences-file[26] ⊗ | Manually sets the initial preferences file. This is required to change the initial preferences when the default file is read-only (eg. on lacros). Passing this flag will reset the preferences regardless of whether this is the first run. ↪
--initialize-client-hints-storage ⊗ | Pre-load the client hint storage. Takes a JSON dict, with each key being an origin (RFC 6454 Section 6.2) and each value a comma-separated list of client hint tokens (RFC 8942 Section 3.1, client-hints-infrastructure Section 7.1). Each origin/token-list entry will be parsed and persisted to the Client Hints storage as though the token-list had come through an Accept-CH response header from a navigation from the origin. The initialization will only apply to non-OffTheRecord profiles, meaning incognito or guest profiles will not have the storage applied. ↪
--input ⊗ | No description ↪
--install-autogenerated-theme ⊗ | Installs an autogenerated theme based on the given RGB value. The format is "r,g,b", where r, g, b are a numeric values from 0 to 255. ↪

--instant-process ⊗ | Marks a renderer as an Instant process. ↪
--integration-test-timeout-minutes ⊗ | Set the timeout for integration tests in minutes. 0 disables the timeout entirely. ↪
--ip-address-space-overrides ⊗ | Specifies manual overrides to the IP endpoint -> IP address space mapping. This allows running local tests against "public" and "private" IP addresses. This switch is specified as a comma-separated list of overrides. Each override is given as a colon-separated ":" pair. Grammar, in pseudo-BNF format: switch := override-list override-list := override â€œ,â€ override-list |  override := ip-endpoint â€œ=â€ address-space address-space := â€œpublicâ€ | â€œprivateâ€ | â€œlocalâ€ ip-endpoint := ip-address ":" port ip-address := see net::ParseURLHostnameToAddress() for details port := integer in the [0-65535] range Any invalid entries in the comma-separated list are ignored. See also the design doc: https://docs.google.com/document/d/1-umCGylIOuSG02k9KGDwKayt3bzBXtGwVlCQHHkIcnQ/edit# And the Web Platform Test RFC #72 behind it: https://github.com/web-platform-tests/rfcs/blob/master/rfcs/address_space_overrides.md ↪
--ip-anonymization-proxy-allow-list ⊗ | Specifies a list of origins on which to use the server specified by kIPAnonymizationProxyServer. if kIPAnonymizationProxyServer is empty this list will be ignored. This is intended as a reverse bypass rules list. ↪
--ip-anonymization-proxy-password ⊗ | Specifies a value for the "password" header to be passed to the proxy specified by kIPAnonymizationProxyServer. if kIPAnonymizationProxyServer is empty this list will be ignored. ↪
--ip-anonymization-proxy-server ⊗ | Specifies a proxy server for origins specified in kIPAnonymizationProxyAllowList. This proxy will be used on a best-effort basis when normal proxy resolution would result in trying direct connections (possibly after trying some other proxy server). ↪
--ipc-connection-timeout ⊗ | Overrides the timeout, in seconds, that a child process waits for a connection from the browser before killing itself. ↪
--ipc-dump-directory[27] ⊗ | Dumps IPC messages sent from renderer processes to the browser process to the given directory. Used primarily to gather samples for IPC fuzzing. ↪
--ipc-fuzzer-testcase[27] ⊗ | Specifies the testcase used by the IPC fuzzer. ↪
--isolate-origins ⊗ | Require dedicated processes for a set of origins, specified as a comma-separated list. For example: --isolate-origins=https://www.foo.com,https://www.bar.com ↪

--kiosk-printing ⊗ | Enable automatically pressing the print button in print preview. ↪
--lacros-availability-ignore ⊗ | When this flag is set, the lacros-availability policy is ignored. ↪
--lacros-chrome-additional-args ⊗ | If this switch is set, then ash-chrome will pass additional arguments when launching lacros-chrome. The string '####' is used as a delimiter. Example: --lacros-chrome-additional-args="--foo=5####--bar=/tmp/dir name". Will result in two arguments passed to lacros-chrome: --foo=5 --bar=/tmp/dir name ↪
--lacros-chrome-additional-args-file ⊗ | If this switch is set, then ash-chrome will read from the provided path and pass additional arguments when launching lacros-chrome. Each non-empty line in the file will be treated as an argument. Example file contents: --foo=5 --bar=/tmp/dir name ↪
--lacros-chrome-additional-env ⊗ | Additional environment variables set for lacros-chrome. The string '####' is used as a delimiter. For example: --lacros-chrome-additional-env=WAYLAND_DEBUG=client####FOO=bar will enable Wayland protocol logging and set FOO=bar. ↪
--lacros-chrome-path ⊗ | If this switch is set, then ash-chrome will exec the lacros-chrome binary from the indicated path rather than from component updater. Note that the path should be to a directory that contains a binary named 'chrome'. ↪
--lacros-mojo-socket-for-testing ⊗ | If set, ash-chrome will drop a Unix domain socket to wait for a process to connect to it, and the connection will be used to request file descriptors from ash-chrome, and when the process forks to start a lacros-chrome, the obtained file descriptor will be used by lacros-chrome to set up the mojo connection with ash-chrome. There are mainly two use cases: 1. Test launcher to run browser tests in testing environment. 2. A terminal to start lacros-chrome with a debugger. ↪
