On other platforms, crashpad_handler is a standalone executable. 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. This binding happens on per-frame basis and hence can potentially be a performance bottleneck. Fallback to XPS. Determines which Google Privacy CA to use for attestation. I can't add the SSO URL to the IE mode list because it then forces all other apps that go through that same SSO URL to also launch in IE mode, which we can't have. Shows a dialog asking the user to try chrome. Turn on Calling GL Error after every command. chromium Makes Content Shell use the given path for its data directory. Some platforms typically have very little 'free' memory, but plenty is available in buffers+cached. Override secondary gpu vendor ids from the GpuInfoCollector. Enables display list based 2d canvas implementation. Renderer process parameter for WebRTC Stun probe trial to determine the interval. The webviewOptions dictionary is used to configure the WebView2 environment when launching a WebView2 app. Microsoft Edge (Chromium) command-line switches The new Microsoft Edge (Chromium) is a classic desktop app that supports command-line arguments as Chrome does. Use this table as a guide to transitioning to Microsoft Edge by comparing how these features are supported in both versions of Microsoft Edge. Values are defined as: 'documentonlytrue' to set the default be true only for document level nodes. Only valid with GPU accelerated compositing + impl-side painting. Valid values are "ltr" (left-to-right) and "rtl" (right-to-left). The constant OS_CHROMEOS must not be defined, and the constant OS_LINUX must be defined. To open Microsoft Edge using Command Prompt refer the steps mentioned below: Type command prompt in the search bar on the Taskbar. Enables Web Platform features that are in development.

Additional query params to insert in the search and instant URLs. Set the value to '1' to enable the feature, and set to '0' to disable. * Each renderer process, for its whole lifetime, is dedicated to rendering pages for just one site. This is different from the Media Session API as it is enabling a default behaviour for the browser. In particular, Edges Startup Boost feature means that theres often a hiddenmsedge.exeinstance hanging around in the background even when all browser windows are closed. Enables remote debug over HTTP on the specified socket name. Enables new profile management system, including lock mode.

If the value doesn't start with !, a program will be debugged if manifest URL matches any pattern. /prefetch:# arguments to use when launching various process types. Disables new profile management system, including new profile chooser UI. I noticed that when startup boost is enabled, it's not longer possible to invoke Edge using the typical Chromium command line switches that can be appended to, e.g., the taskbar icon in order to run Edge/Chromium with certain parameters, or from cmd. Microsoft Edge kiosk mode offers two lockdown experiences of the browser so organizations can create, manage, and provide the best experience for their customers. Allows debugging of sandboxed processes (see zygote_main_linux.cc). Enables multiple account versions of chrome.identity APIs. If this switch is set, the device cannot be remotely disabled by its owner. The default is chrome-profile-{pid} for the browser and test-profile-{pid} for tests. When blink should declare a load "done" for the purpose of the progress bar. Because it's buggy, the user must explicitly enable it so that visiting a random webpage can't cause instability.

Browser tests may need to add this switch so that at least one browser instance is created on startup. This is generally only useful for tests that want to force disabling. This hides certain system UI elements and forces the app to be installed if it hasn't been already. If persistence of a command line option is broadly desired, we may promote it to a persistently-configurable location (e.g. {count} if present will be incremented each time a profile is generated for this process. TODO(dalecurtis): Remove once experiments for http://crbug.com/470940 finish.

The contents of this flag are prepended to the renderer command line. Note this doesn't prevent the app list from running, it just makes Chrome think the app list hasn't been enabled (as in kEnableAppList) yet. Microsoft Edge will now open normally. By default the throttler is only enabled for a hard-coded list of plugins. ("-inl" suffixes are also disregarded for this matching). The period of an ALSA output device determines how many frames elapse between hardware interrupts. Disables password generation when we detect that the user is going through account creation. The disable-renderer-accessibility switch overrides this if present. Used, like |kForceDirectShowVideoCapture|, to troubleshoot problems in Windows platforms.

Used for testing. Disables GL drawing operations which produce pixel output. Enforces a one-site-per-process security policy: Note that for WebRTC calls we'll treat the bits as if they came from the microphone, which means you should disable audio processing (lest your audio file will play back distorted). Each argument accepts a comma-delimited list of feature names, like so: Unfortunately, theres no documented list of feature names, although the features inherited from upstream can be found in the Chromium-source code, often in one of many files named features.cc. Use a Mojo-based LocalStorage implementation. Values are case sensitive and based on Shill names in service_constants.h. Enables starting the ARC instance upon session start.
