Supported APIs for Microsoft Edge extensions

  • 아티클

Microsoft Edge extensions use a subset of the JavaScript methods for the Chromium browser engine platform. When building an extension for the Microsoft Edge browser, you can use the following APIs.

API Description Manifest versions
accessibilityFeatures Manages the browser's accessibility features. MV2, MV3
action Controls the extension's icon in the browser's toolbar. MV3
alarms Schedules code to run periodically or at a specified time in the future. MV2, MV3
bookmarks Creates, organizes, and manipulates bookmarks. MV2, MV3
browserAction Uses browser actions to place icons on the toolbar in Microsoft Edge. You can also use browser actions to add a tooltip, badge, or popup. MV2

commands Adds keyboard shortcuts that trigger actions in your extension, such as an action to open the browser or send a command to the extension. MV2, MV3

declarativeContent Performs actions depending on the content of a page, without requiring permission to read the page content. MV2, MV3
declarativeNetRequest Provides more privacy by blocking or modifying network requests by specifying declarative rules. Allows extensions to modify network requests without intercepting the request and viewing the content. MV2, MV3

devtools.panels Integrates your extension into the Developer Tools window UI by creating your own panels, accessing existing panels, or adding sidebars. MV2, MV3
dns Resolves DNS addresses. MV2, MV3. Dev channel.
dom Accesses special DOM APIs for Extensions. MV2, MV3
downloads Programmatically starts, monitors, manipulates, and searches for downloads. MV2, MV3
enterprise.hardwarePlatform Gets the manufacturer and model of the hardware platform where the browser runs. For extensions that are installed by enterprise policy. MV2, MV3
events Common types used by APIs that raise events to notify you when an interesting event occurs. MV2, MV3
extension Utilities that can be used by any extension page. Includes support for exchanging messages between an extension and its content scripts, or between extensions. MV2, MV3
extensionTypes Type declarations for Microsoft Edge extensions. MV2, MV3
fontSettings Manages font settings in Microsoft Edge. MV2, MV3
history Interacts with the browser's record of visited pages. You can add, remove, or query for URLs in the browser's history. To override the history page with your own version, navigate to Override Pages. MV2, MV3
i18n Implements internationalization across your whole app or extension. MV2, MV3
identity Gets OAuth2 access tokens. Not supported: identity.getAccounts, identity.getAuthToken - As an alternate, you can use identity.launchWebAuthFlow to fetch an OAuth2 token to authenticate users. MV2, MV3
idle Detects when the machine's idle state changes. MV2, MV3
input.ime Implements a custom IME for the OS, allowing an extension to handle keystrokes, set the composition, and manage the candidate window. MV2, MV3
management Manages the list of installed or running extensions. Can override the built-in New Tab page. MV2, MV3
notifications Creates rich notifications using templates and displays them in the system tray. MV2, MV3

privacy Controls features in Microsoft Edge that affects a user's privacy. This API depends on the EdgeSetting prototype of types to get and set the configuration of Microsoft Edge. MV2, MV3
processes Interacts with the browser's processes. MV2, MV3. Dev channel.
proxy Manages proxy settings for Microsoft Edge. This API depends on the EdgeSetting prototype of the types API to get and set the proxy configuration of Microsoft Edge. MV2, MV3
runtime Retrieves the background page, return details about the manifest, and listen for and respond to events in the app or extension lifecycle. You can also convert the relative path of URLs to fully qualified URLs. MV2, MV3
scripting Executes scripts in different contexts. MV3
search Searches by using the default provider. MV2, MV3
sessions Queries and restores tabs and windows from a browsing session. MV2, MV3

tts Plays synthesized text-to-speech (TTS). MV2, MV3
ttsEngine Implements a text-to-speech (TTS) engine using an extension. Extensions that register to use this API receive events that contain utterances to be spoken and other parameters.

types Type declarations for Microsoft Edge. MV2, MV3
userScripts Executes user scripts in the User Scripts context. MV3
webAuthenticationProxy Lets remote desktop software that's running on a remote host intercept Web Authentication API (WebAuthn) requests in order to handle them on a local client. MV3

Additional considerations for supported APIs

  • The user must be signed into Microsoft Edge using a Microsoft account (MSA) or Microsoft Entra ID account to use chrome.identity.getProfileUserInfo. If the user is signed into Microsoft Edge using an on-premises Microsoft Entra ID account, the API returns null for the email and ID values.

    A Microsoft account (MSA) is an Outlook.com, Live.com, or Hotmail.com account.

  • Microsoft Edge doesn't support extensions that use Chrome Web Store payments because it uses identity.getAuthtoken to request tokens for signed-in users. These tokens are sent to the REST-based licensing API.
