AudioServiceSandbox | Enables the audio-service sandbox. This feature has an effect only when the kAudioServiceOutOfProcess feature is enabled. | ❌ |
BackgroundFetch | Kill switch for Background Fetch. | ✅ |
BackForwardCache | Enable using the BackForwardCache. | ✅ |
BackForwardTransitions | Enable showing a page preview during back/forward navigations. | ❌ |
BackForwardCacheMediaSessionService | Allows pages that created a MediaSession service to stay eligible for the back/forward cache. | ✅ |
BackForwardCacheEntryTimeout | Set a time limit for the page to enter the cache. Disabling this prevents flakes during testing. | ✅ |
BackForwardCacheMemoryControls | BackForwardCacheMemoryControls is enabled only on Android to disable BackForwardCache for lower memory devices due to memory limiations. | ❌ |
BlockCrossOriginInitiatedAboutSrcdocNavigations | When enabled, attempts to navigate an iframe by an initiator that isn't same-origin to the iframe's parent are blocked. Exceptions are: (i) same- document navigations when the frame is already about:srcdoc, and (ii) when an about:srcdoc frame reloads itself. This feature is enabled by default, and is intended to be used as a kill-switch if the new behaviour causes problems. TODO(https://crbug.com/328279696): remove this when the blocking feature is fully launched. | ✅ |
BlockInsecurePrivateNetworkRequests | When this feature is enabled, private network requests initiated from
non-secure contexts in the | ✅ |
BlockInsecurePrivateNetworkRequestsFromPrivate | When this feature is enabled, requests to localhost initiated from non-secure
contexts in the | ❌ |

BrowserVerifiedUserActivationMouse | When enabled, mouse user activation will be verified by the browser side. | ❌ |
CacheControlNoStoreEnterBackForwardCache | Allows pages with cache-control:no-store to enter the back/forward cache. Feature params can specify whether pages with cache-control:no-store can be restored if cookies change / if HTTPOnly cookies change. TODO(crbug.com/1228611): Enable this feature. | ❌ |
CapturedSurfaceControlKillswitch | This killswitch is distinct from the OT. It allows us to remotely disable the feature, and get it to stop working even on sites that are in possession of a valid token. When that happens, all API calls gated by the killswitch will fail graceully. | ✅ |
CdmStorageDatabase | This serves as an overall kill switch to kill CdmStorageDatabase. If disabled, which it is by default, no operations will be routed through the CdmStorage path, even in the migration code that lives in MediaLicense code path. | ❌ |
CdmStorageDatabaseMigration | This guards between using the MediaLicense code path and the CdmStorage code path for storing Cdm data. This will be enabled by default as we do not want the CdmStorageDatabase to be used solely, and instead when we conduct our experiments, we will enable kCdmStorageDatabase to flow the migration. Later when the migration is finished, we will remove this flag so that kCdmStorageDatabase serves as the only flag. Refer to go/cdm-storage-migration-details for more details. | ✅ |

IsolatedWebApps | Enable support for isolated web apps. This will guard features like serving isolated web apps via the isolated-app:// scheme, and other advanced isolated app functionality. See https://github.com/reillyeon/isolated-web-apps for a general overview. This also enables support for Controlled Frame, providing the Controlled Frame tag to IWA apps assuming that Controlled Frame isn't otherwise disabled via the kControlledFrame feature. See https://github.com/WICG/controlled-frame/blob/main/README.md for more info. Please don't use this feature flag directly to guard the IWA code. Use IsolatedWebAppsPolicy::AreIsolatedWebAppsEnabled() in the browser process or check kEnableIsolatedWebAppsInRenderer command line flag in the renderer process. | ❌ |
AutomaticFullscreenContentSetting | Enables a new Automatic Fullscreen content setting that lets allowlisted origins use the HTML Fullscreen API without transient activation. | ❌ |
IsolateFencedFrames | Enables process isolation of fenced content (content inside fenced frames) from non-fenced content. See https://github.com/WICG/fenced-frame/blob/master/explainer/process_isolation.md for rationale and more details. | ❌ |

MainThreadCompositingPriority | Uses ThreadType::kCompositing for the main thread | ✅ |
MBIMode | The MBI mode controls whether or not communication over the AgentSchedulingGroup is ordered with respect to the render-process-global legacy IPC channel, as well as the granularity of AgentSchedulingGroup creation. This will break ordering guarantees between different agent scheduling groups (ordering withing a group is still preserved). DO NOT USE! The feature is not yet fully implemented. See crbug.com/1111231. | ❌ |
NavigationNetworkResponseQueue | When NavigationNetworkResponseQueue is enabled, the browser will schedule some tasks related to navigation network responses in a kHigh priority queue. | ✅ |

RetryGetVideoCaptureDeviceInfos | Enables retrying to obtain list of available cameras after restarting the video capture service if a previous attempt failed, which could be caused by a service crash. | ❌ |
ProcessPerSiteUpToMainFrameThreshold | Reuses RenderProcessHost up to a certain threshold. This mode ignores the soft process limit and behaves just like a process-per-site policy for all sites, with an additional restriction that a process may only be reused while the number of main frames in that process stays below a threshold. | ❌ |
ServiceWorkerBypassFetchHandler | Enables bypassing the service worker fetch handler. Unlike
| ❌ |
ServiceWorkerSkipIgnorableFetchHandler | Enables skipping the service worker fetch handler if the fetch handler is identified as ignorable. | ✅ |

SecurePaymentConfirmationBrowser | Browser-side feature flag for Secure Payment Confirmation (SPC) that also controls the render side feature state. SPC is not currently available on Linux or ChromeOS, as it requires platform authenticator support. | ❌ |
SecurePaymentConfirmationDebug | Used to control whether to remove the restriction that PaymentCredential in WebAuthn and secure payment confirmation method in PaymentRequest API must use a user verifying platform authenticator. When enabled, this allows using such devices as UbiKey on Linux, which can make development easier. | ❌ |
ServiceWorkerPaymentApps | Service worker based payment apps as defined by w3c here: https://w3c.github.io/webpayments-payment-apps-api/ TODO(rouslan): Remove this. | ✅ |
SharedArrayBuffer | http://tc39.github.io/ecmascript_sharedmem/shmem.html This feature is also enabled independently of this flag for cross-origin isolated renderers. | ❌ |

WebLockScreenApi | Enable the web lockscreen API implementation (https://github.com/WICG/lock-screen) in Chrome. | ❌ |
SiteInstanceGroupsForDataUrls | When enabled, puts subframe data: URLs in a separate SiteInstance in the same SiteInstanceGroup as the initiator. | ❌ |
SiteIsolationForCrossOriginOpenerPolicy | Controls whether to isolate sites of documents that specify an eligible Cross-Origin-Opener-Policy header. Note that this is only intended to be used on Android, which does not use strict site isolation. See https://crbug.com/1018656. | ❌ |
DisableProcessReuse | When enabled, OOPIFs will not try to reuse compatible processes from unrelated tabs. | ❌ |
SpareRendererForSitePerProcess | Controls whether SpareRenderProcessHostManager tries to always have a warm spare renderer process around for the most recently requested BrowserContext. This feature is only consulted in site-per-process mode. | ✅ |
StrictOriginIsolation | Controls whether site isolation should use origins instead of scheme and eTLD+1. | ❌ |
SuppressDifferentOriginSubframeJSDialogs | Disallows window.{alert, prompt, confirm} if triggered inside a subframe that is not same origin with the main frame. | ❌ |

SyntheticPointerActions | Dispatch touch events to "SyntheticGestureController" for events from Devtool Protocol Input.dispatchTouchEvent to simulate touch events close to real OS events. | ❌ |
TouchDragAndContextMenu | This feature allows touch dragging and a context menu to occur simultaneously, with the assumption that the menu is non-modal. Without this feature, a long-press touch gesture can start either a drag or a context-menu in Blink, not both (more precisely, a context menu is shown only if a drag cannot be started). | ❌ |
UnrestrictedSharedArrayBuffer | This feature is for a reverse Origin Trial, enabling SharedArrayBuffer for sites as they migrate towards requiring cross-origin isolation for these features. TODO(bbudge): Remove when the deprecation is complete. https://developer.chrome.com/origintrials/#/view_trial/303992974847508481 https://crbug.com/1144104 | ❌ |
UserActivationSameOriginVisibility | Allows user activation propagation to all frames having the same origin as the activation notifier frame. This is an intermediate measure before we have an iframe attribute to declaratively allow user activation propagation to subframes. | ✅ |
VerifyDidCommitParams | Enables comparing browser and renderer's DidCommitProvisionalLoadParams in RenderFrameHostImpl::VerifyThatBrowserAndRendererCalculatedDidCommitParamsMatch. | ✅ |
ViewportSegments | Enable the viewport segments API. Tracking bug for enabling viewport segments API: https://crbug.com/1039050. | ❌ |

SoftNavigationDetection | Used to enable the code for detecting soft navigations through task attribution. Set to stable as this generates an enabled-by-default base::Feature for a field-trial remote shutoff. Needs to be a runtime feature so that the Soft Navigation Heuristics Origin Trial can depend on it. | ✅ |

TouchDragAndContextMenu | This feature allows touch dragging and a context menu to occur simultaneously, with the assumption that the menu is non-modal. Without this feature, a long-press touch gesture can start either a drag or a context-menu in Blink, not both (more precisely, a context menu is shown only if a drag cannot be started). | ❌ |
TouchDragOnShortPress | This feature makes touch dragging to occur at the short-press gesture, which occurs right before the long-press gesture. This feature assumes that TouchDragAndContextMenu is enabled. | ❌ |
TouchEventFeatureDetection | Many websites disable mouse support when touch APIs are available. We'd like to enable this always but can't until more websites fix this bug. Chromium sets this conditionally (eg. based on the presence of a touchscreen) in ApplyWebPreferences. "Touch events" themselves are always enabled since they're a feature always supported by Chrome. | ✅ |

WakeLock | The "WakeLock" feature was originally implied_by "ScreenWakeLock" and "SystemWakeLock". The former was removed after being promoted to stable, but we need to keep this feature around for code and IDLs that should work with both screen and system wake locks. | ✅ |
