Stable release date: September 30th, 2025
Unless otherwise noted, the following changes apply to Chrome 141 stable channel release for Android, ChromeOS, Linux, macOS, and Windows.
CSS
Custom property enumeration in getComputedStyle()
When iterating over window.getComputedStyle(element) in Chrome, there was a bug
where it forgets to include any custom properties set on the element. Therefore, length()
on the returned object forgets to account for the number of custom properties
set. This bug is fixed from Chrome 141, aligning Chrome
with Firefox and Safari.
DOM
ARIA Notify API
ariaNotify provides a JavaScript API that lets content authors tell a screen
reader what to read.
ariaNotify improves reliability and developer control compared to ARIA live
regions, allowing for announcing changes not tied to DOM updates. This enables
more consistent and ergonomic accessibility experiences across dynamic web
applications. Iframe usage of this feature can be controlled using the
"aria-notify" permission policy.

Update hidden=until-found and details ancestor revealing algorithm
The specification recently had some small changes to the revealing algorithms
for hidden=until-found and details elements to prevent the browser from
getting stuck in an infinite loop, these are now shipping in Chrome.

JavaScript
Align implementations on when RTP stats should be created
RTP stats objects, of type "outbound-rtp" or "inbound-rtp" in this case, represents a WebRTC stream. The identifier of this stream is the SSRC (a number). This feature aligns with the specification on when these stats should be created.

Media
Support restrictOwnAudio
The restrictOwnAudio property is a captured display surfaces constrainable
property. It changes the behavior of system audio in a captured display surface.
The restrictOwnAudio constraint only has an effect if the captured display
surface inherently includes system audio; otherwise, it will have no impact.
windowAudio for getDisplayMedia()
Extends DisplayMediaStreamOptions for getDisplayMedia() with a windowAudio
option. This new option allows web applications to hint to the user agent
whether the user should be offered the ability to share audio when a window is
selected. windowAudio can be set to exclude, system, or window based on
application preference.
A web application that is configured for audio capture but wants to limit system
audio capture when a window is selected should set windowAudio: "exclude".
Miscellaneous
Support width and height as presentation attributes on nested <svg> elements
This feature supports applying width and height as presentation attributes on
nested <svg> elements through both SVG markup and CSS. This dual approach
provides even greater flexibility for developers, allowing them to manage and
style SVG elements more efficiently within complex designs.

Digital Credentials API (presentation support)
Websites retrieve credentials from mobile wallet apps using a variety of
mechanisms, such as custom URL handlers and QR code scanning. This feature lets
sites request identity information from wallets using Android's
IdentityCredential CredMan system. It is extensible to support multiple
credential formats (such as ISO mDoc and W3C verifiable credential) and allows
multiple wallet apps to be used. This update adds mechanisms to help reduce the
risk of ecosystem-scale abuse of real-world identity.

Navigation API: deferred commit (precommit handlers)
Normally, when navigateEvent.intercept() is called, the intercepted navigation
commits (and therefore the URL updates) as soon as the NavigateEvent finishes
dispatch.
This feature adds a precommitHandler option to navigateEvent.intercept(),
similar to handler. It defers the commit until that handler (and all other
precommit handlers) are resolved, and it allows the handler to change the
navigation's URL, info, status, and history handling behavior (push/replace).

FedCM: Alternative fields in account selection
Adds support for phone numbers and usernames, in addition to or instead of a user's full name and email address as identifiers for disambiguating accounts in the account selector. Also, makes these new fields available for websites to affect the disclosure text.
Tracking bug #382086282 | ChromeStatus.com entry | Spec
Network / Connectivity
No-Vary-Search support for the HTTP disk cache
Lets the HTTP disk cache use the No-Vary-Search response header to share a
cache entry between URLs that differ only in the query parameters.
Developers can use No-Vary-Search to specify query parameters that have no
impact on the user experience. A common example might be an ID used to track
conversions. Supporting this header in the HTTP disk cache means that if the
user later goes back to that same page without the conversion ID, it can be used
or revalidated from the cache rather than having to be fetched from scratch from
the network.
Previously, No-Vary-Search support shipped for the navigation prefetch cache,
prefetch and prerender speculation rules, and prerender. This launch makes it
generally available to any feature that uses the HTTP disk cache.

Offline / Storage
IndexedDB getAllRecords() and direction option for getAll() and getAllKeys()
This feature adds the getAllRecords() method to the IndexedDB IDBObjectStore and IDBIndex. It also adds a direction parameter to getAll() and getAllKeys(). This functionality lets certain read patterns be significantly faster when compared to the existing alternative of iteration with cursors. In one test, a workload from a Microsoft property showed a 350ms improvement.
The getAllRecords() method combines getAllKeys() and getAll() by enumerating both primary keys and values at the same time. For an IDBIndex, getAllRecords() also provides the record's index key in addition to the primary key and value.

Performance
Speculation rules: desktop "eager" eagerness improvements
On desktop, "eager" eagerness speculation rules prefetches and prerenders now trigger when users hover on a link for a shorter time than the "moderate" mouse hover time.
The previous behavior, of starting prefetch and prerenders as soon as possible, was the same as "immediate" eagerness. This new behavior is more useful as it better reflects the author's intent to be more eager than the "moderate" and less eager than "immediate".
Security
Strict Same Origin Policy for Storage Access API
Adjusts the Storage Access API semantics to strictly follow the Same Origin Policy with regard to security. That is, using document.requestStorageAccess() in a frame only attaches cookies to requests to the iframe's origin (not site) by default.
Tracking bug #379030052 | ChromeStatus.com entry | Spec
Signature-based Integrity
This feature provides web developers with a mechanism to verify the provenance of resources they depend upon, creating a technical foundation for trust in a site's dependencies. In short: servers can sign responses with a Ed25519 key pair, and web developers can require the user agent to verify the signature using a specific public key. This offers a helpful addition to URL-based checks offered by Content Security Policy on the one hand, and Subresource Integrity's content-based checks on the other.

WebRTC
WebRTC Encoded Transform (V2)
This API allows processing of encoded media flowing through an
RTCPeerConnection. Chrome shipped an early version of this API in 2020. Since
then, the specification has changed and other browsers have shipped the updated version
(Safari in 2022 and Firefox in 2023). This launch aligns Chrome with
the updated specification as part of Interop 2025.
This launch does not cover the generateKeyFrame method, which is still under
discussion.

echoCancellationMode for getUserMedia()
Extends the echoCancellation behavior of the MediaTrackConstraints dictionary.
his previously accepted true or false and now additionally accepts the values
"all" and "remote-only". This lets clients modify
echo cancellation behavior applied to audio tracks received from microphones,
controlling how much of the user system playout (all, or only audio received
from PeerConnections) is removed from the microphone signal.
Managed ChromeOS only
Permissions Policy for Device Attributes API
The new Permissions Policy enables restricting access to the Device Attributes API, which is available only for policy-installed kiosk web apps and policy-installed Isolated Web Apps, both only on managed ChromeOS devices.
Additionally, the feature is controlled by content settings. Two new policies
are introduced: DeviceAttributesBlockedForOrigins and
DefaultDeviceAttributesSetting, to complement previously introduced
DeviceAttributesAllowedForOrigins. The feature is enabled by default for
policy-installed kiosk web apps and policy-installed Isolated Web Apps on
managed ChromeOS devices.
Origin trials
Local network access restrictions
Chrome 141 restricts the ability to make requests to the user's local network, gated behind a permission prompt.
This origin trial temporarily allows for access to resources on local networks to originate from non-secure contexts. This will give developers more time to migrate Local Network Access requests to originate from a secure context.

Proofreader API
A JavaScript API for proofreading input text with suggested corrections, backed by an AI language model.

Extend CSP script-src (also known as script-src-v2)
This feature adds new keywords to the script-src Content Security Policy (CSP) directive. This adds two new hash-based allowlisting mechanisms: script sources based on hashes of URLs and contents of eval() and eval()-like functions. This is sometimes referred to as script-src-v2, although it is backward compatible with the existing script-src, and uses the same directive.
Extending hashes to cover URL and eval() hashes lets developers set reasonably strict security policies by narrowly allowlisting scripts by their hashes even when script contents are subject to frequent changes, and known-safe contents of eval() without permitting unchecked use of eval() broadly.
The new keywords override host-based script-src when provided. This allows a single header to be compatible with browsers that both do or do not implement the new keywords.

WebAssembly custom descriptors
Lets WebAssembly store data associated with source-level types more efficiently in new "custom descriptor" objects. These custom descriptors can be configured with prototypes for the WebAssembly objects of that source-level type. This lets you install methods on a WebAssembly object's prototype chain and call them directly from JavaScript using normal method call syntax. The prototypes and methods can be configured declaratively using an imported built-in function.

Deprecations and removals
Stop sending Purpose: prefetch header from prefetches and prerenders
Now that prefetches and prerenders are using the Sec-Purpose header for
prefetches and prerenders, we will move to remove the legacy Purpose: prefetch
header that is still currently passed. This will be behind a feature flag/ kill
switch to prevent compat issues.
This will be scoped to speculation rules prefetch, speculation rules prerender, , and Chromium's non-standard .
