Developer policies for the Microsoft Edge Add-ons store

To develop an extension to be published through the Microsoft Edge Add-ons store, follow these policies. These policies apply to submitting extensions through Partner Center and publishing the extensions at the Microsoft Edge Add-ons store.

The Microsoft Edge Add-ons store is also called the Edge Add-ons store, the Microsoft Edge Add-ons website, or the Edge Add-ons website.


The following principles are reflected in these developer policies:

  • Offer unique and distinct value within your extension for Microsoft Edge. Provide a compelling reason to download your extension from the Microsoft Edge Add-ons store.

  • Do not mislead users about what your extension does, who is offering it, and so on.

  • Do not attempt to cheat users, the system, or the ecosystem. There is no place in Microsoft Edge Add-ons for any kind of fraud; be it ratings and review manipulation, credit card fraud, or other fraudulent activity.

Adhering to these policies for the Microsoft Edge Add-ons store helps you make choices that enhance the appeal and audience of your extension.

Building quality products

Microsoft is committed to delivering quality products to its customers. Therefore, extensions which don't follow the quality guidelines aren't allowed, such as:

  • Content deemed not family-friendly.

  • Bots: Any extension that automatically generates spam-like or unsolicited messages on the user's behalf, or that performs automated actions to manipulate a platform's features, such as artificially inflating engagement metrics.

  • Cryptocurrency: Crypto mining and any other illegitimate activities that involve crypto wallets and currency.

  • Non-production builds: For example, an extension that's still in an experimental stage, that's prone to crashes or instability, or that's designed for internal testing purposes only and not intended for public release.

  • Prohibited products: An extension that promotes or facilitates the sale of illegal drugs, firearms, or counterfeit goods would be considered a prohibited product, and any extension that violates intellectual property rights, such as offering pirated software or copyrighted content without authorization, would be restricted.

  • Gambling content.

1. Product policies

1.1 Distinct function and value; accurate representation

Your extension and associated metadata must accurately and clearly reflect the source, functionality, and features that you describe.

1.1.1 Extensions must have a single purpose

Your extension must have a single purpose with narrow functionality. For example, your extension cannot function as a simple calculator and as a code remote scanner simultaneously.

1.1.2 Describe your extension

All aspects of your extension should accurately describe the functions, features and any important limitations of your extension, including required or supported input devices. The value proposition of your extension must be clear during the first run experience. Your extension may not use a name or icon similar to that of other extensions, must not reference other browsers, and must not claim to represent a company, government body, or other entity if you don't have permission to make that representation.

If screenshots are provided, they must:

  • Be clear and informative.
  • Render properly; for example, must not be stretched or blurry.

All functionality of an extension should be clearly disclosed to the user. Any extension that attempts to deceive or mislead users will be removed from the store.

1.1.3 Functionality

Your extension must be fully functional, as in, there should not be any blockers, including but not limited to, broken URLs or blocked webpage links.

1.1.4 Search and discovery

Search terms may not exceed seven unique terms, and should be relevant to your extension.

Extensions with obfuscated code aren't allowed. This includes code within your extension package, as well as any external code or resource fetched from the web. You may be asked to refactor parts of your code, if it is not reviewable.

1.1.8 Altering browser settings

Your extension must not, without appropriate user consent, alter, or appear to alter, browser functionality or settings including, but not limited to: the address bar search provider and suggestions, the start or home page, the new tab page, and adding or removing favorites.

Any changes made to the device settings must be done with the user's knowledge and consent, and must be easily reversible by the user.

Any alteration of browser settings, such as new tabs and search engines, should be mentioned in the listing or description, and such alterations should use standard APIs to achieve that functionality. They must not override default settings without user permission.

1.2 Security

Extensions must declare all permissions that are required for their functionality in the manifest. Your extension must only request those permissions that are essential for functioning.

Any declarativeNetRequest rules must be clearly declared within the extension, and should not be imported remotely unless necessary for functionality.

Extensions must not promote deceptive installation of other extensions.

Bulk submissions of extensions with the same functionality and code are not allowed.

Extensions should not exploit security vulnerabilities of other extensions or applications, and must keep authentication information secure.

Extensions that function as crypto wallets can only be published by verified company accounts.

In general, your extension must not jeopardize or compromise user security, or the security or functionality of the device, system, or related systems.

1.2.1 Content security policies

If you make any changes to your extension beyond the described functionality, any changes to code must be compliant with the Content Security Policy for Microsoft Edge extensions; see Content Security Policy (CSP). For example, your extension should not download a remote script and subsequently run that script in a manner that is not consistent with the described functionality.

1.2.2 Unwanted and malicious software

Your extension must not contain or enable malware that may harm the operation of the network, servers, and infrastructure of Microsoft or any third parties. Spyware, malicious scripts, and phishing scams are also prohibited.

Your extension must comply with the Microsoft criteria for unwanted and malicious software, listed in How Microsoft identifies malware and potentially unwanted applications.

1.2.3 Dependency on other software

Your extension may depend on non-integrated software (such as another product, module, or service) to deliver the primary functionality. However, this information should be clearly disclosed in the description.

1.2.4 Extension updates

Unless otherwise permitted by Microsoft, your extension must be updated only through Partner Center and the Edge Add-ons store.

Any data that's collected should be aggregated and anonymized, and must used in accordance with applicable privacy and other jurisdictional legal requirements.

If you provide Microsoft with your privacy policy, then you agree to permit Microsoft to share such privacy policy with users of your extension.

1.5.3 Sharing data with third parties

You may publish the personal information of users of your extension to an outside service or third-party through your extension or associated metadata only after obtaining opt-in consent from those users. Opt-in consent means the users give their express permission in the user interface of your extension for the requested activity, after you:
