Troubleshooting Chrome Web Store violations

Published on Updated on

This page is provided to help you understand why your extension was rejected or removed from the Chrome Web Store and how you can fix the violation.

Each section in this document describes the issues that correspond to a particular category of violation. In order to make it easier to reference specific violations, the Chrome Web Store assigns each violation a human-readable ID. These IDs are composed of two words: a color and an element. For example, Yellow Magnesium corresponds to the general class of errors where the extension does not behave as expected.

Functionality not working

Corresponds to notification ID: Yellow Magnesium

The intent of this policy is to ensure a minimum quality level for all items published in the Chrome Web Store. Extensions should provide the functionality described in their listings and, if they cannot, communicate that to the user.

Common reasons for removal/rejection

  • Your item has packaging errors. Examples:
    • There are files mentioned in your manifest that are not present in your package. This is most commonly seen with image files.
    • The path or name of the files mentioned in your package are incorrect
  • A functionality in your item is not working due to a server side issue at the time of reviewing.
  • Your item is just not functioning as it expected based on the item's listing.

How can you rectify this?

  • Test the code that you submit to the web store locally.
    • Test the exact files that you submit to the web store, not just a local development version of your extension. This may mean extracting resources from the package that you submitted.
    • Unpacked and packed extensions can have different behaviors. Make sure that Chrome loads a packed version of your extension as expected by manually packing your extension and dragging the generated .crx file onto the chrome://extensions page.
  • Verify that your submission contains the files you expect at the paths you expect.
    • Ensure that all the files mentioned in your manifest.json are present in the package and their names and paths are correct.
    • Check for case sensitivity bugs. For example, say your background script was named Background.js, but your manifest.json references background.js. Some file systems will treat these as the same file while others will treat them as two distinct files, causing Chrome to error when loading the extension.
  • Make sure that your extensions clearly communicate error conditions to the user.
    • It should be as obvious as possible for new users to understand how your extension works and verify it's behaving correctly.
    • If your extension requires an account or special network environment, make sure that requirement is communicated to the user. If these conditions are not met, consider ways that you can make the user aware that the extension will not work as expected.
    • Test your experience on an unreliable internet connection (e.g. lie-fi). The extension's UI should gracefully handle request timeouts, HTTP 400 and 500 errors, certificate timeouts, and other such error conditions.
  • If you cannot determine why the reviewer thought that your extension was not working as expected, contact developer support to request more information about the rejection.
    • In some cases, reviewers may encounter issues you cannot reproduce. Use the developer support contact form to request clarification about what features or user flows did not behave as expected.

Relevant policy

This section addresses extensions that are in violation of the following section of the Chrome Web Store developer program policies:

Spam & Placement in the Store

Functionality: Do not post an extension with a single purpose of installing or launching another app, theme, webpage, or extension. Extensions with broken functionality—such as dead sites or non-functioning features—are not allowed.

Excessive permissions

Corresponds to notification ID: Purple Potassium

The intent of this policy is to prevent excessive and unnecessary access to user data by extensions.

Common reasons for removal/rejection

  • The extension is requesting a permission but not using it.
  • The extension is requesting a permission that is not required to implement the functionality the extension provides.

Commonly misunderstood permissions

activeTab

This permission grants temporary access to a tab in response to a user invoking your extension. It DOES NOT grant passive access to the user's currently focused tab.

  • When is it required?
    • When you need temporary access to a tab after the user invokes your extension.
  • When is it NOT required?
    • When the extension has access to broad host permissions or host permissions for the specific domains that are relevant to the extension's operations.
    • When using methods on the action, browserAction, pageAction APIs. These APIs can use activeTab to grant temporary host permissions for the currently focused tab, but they do not need activeTab to function.
    • When using tabs.sendMessage to send a message to a specific tab.
    • For basic use of tabs.query, such as querying the user's current tab.

tabs

This permission ONLY grants access to the url, pendingUrl, title, or favIconUrl properties of Tab objects.

  • When is it required?
    • When an extension does not have broad host access, but needs to be able to read sensitive data like the URL of an arbitrary tab.
  • When is it NOT required?
    • When using methods on the tabs API.
    • When the extension has access to broad host permissions. Host permissions grant the extension access to the same data as well as other capabilities.

cookies

This exposes the chrome.cookies API and allows the extension to modify cookies on origins that it has host permissions to access.

storage

The storage permission exposes the chrome.storage API to the extension.

How can you rectify this?

  • Review the list of commonly misunderstood permissions to see if you have committed one of the mistakes listed there.
  • Request only the narrowest permission required to implement your extension's functionality.
  • Remove all unused permissions from your manifests.json's permissions, optional_permissions, and host_permissions arrays.
  • If the message from review does not contain enough information to determine which permissions were considered excessive, contact developer support to request more information about the rejection.
  • If the reviewer indicated that your extension did not use a given permission but you believe it does, contact developer support to appeal the decision and to provide a detailed explanation of why the permission is necessary and how it is used.

Relevant policy

This section addresses extensions that are in violation of the following section of the Chrome Web Store developer program policies:

Use of Permissions

Request access to the narrowest permissions necessary to implement your Product's features or services. If more than one permission could be used to implement a feature, you must request those with the least access to data or functionality.

Don't attempt to "future proof" your Product by requesting a permission that might benefit services or features that have not yet been implemented.

Missing or insufficient metadata

Corresponds to notification ID: Yellow Zinc

The intent of this policy is to ensure a basic quality level of all items in the Chrome Web Store. Users should be able to understand what features and functionality an item provides based on its listing before they choose to install it. Items that misrepresent their capabilities or fail to disclose important information may be subject to enforcement action.

Common reasons for removal/rejection

  • The extension is missing an icon, title, screenshot, or description.
  • The extension's title is not meaningful or is misleading.
  • The extension's screenshots or description is not meaningful or doesn't adequately explain the functionality it provides.

How can you rectify this?

  • Ensure the extension has a meaningful icon, title, screenshots, and description.
  • Clearly explain the extension's functionality in the description and screenshots.
    • List all major features the extension provides.
  • Review the rectification guidance in the Functionality not working section.

Relevant policy

This section addresses extensions that are in violation of the following section of the Chrome Web Store developer program policies:

Content Policies

Impersonation or Deceptive Behavior:
If your product has a blank description field or is missing an icon or screenshots, it will be rejected. If any of your product's content, title, icon, description, or screenshots contains false or misleading information, we may remove it.

Deceptive behavior

Corresponds to notification IDs: Red Nickel, Red Potassium, and Red Silicon

The intent of this policy is to prevent extensions from deceiving or misleading the users.

Common reasons for removal/rejection

  • The extension does not provide the functionality described in the metadata1.
  • The extension provides different functionality than what is described in the metadata1.
  • The extension performs actions not mentioned in the metadata1.
  • The extension impersonates another entity2.
  • The extension copies or is copied from another entity2.
  • The extension pretends to be authorized by another entity2.

1 Metadata means the title, icon, description, screenshots, and other developer-provided information specified in the developer dashboard.

2 An entity here means any company, organization, or extension.

How can you rectify this?

  • Ensure the functionality promised by your extension is working as intended.
  • Clearly state the functionality of your extension in the metadata.
  • Do not perform actions not mentioned in the metadata.
  • Do not pretend to be another entity.
  • Do not copy another extension. You may offer the same functionality as another extension but do not copy from other extensions.
  • Do not pretend that your extension was endorsed, authorized or produced by another entity.

Relevant policy

This section addresses extensions that are in violation of the following section of the Chrome Web Store developer program policies:

Content Policies

Impersonation or Deceptive Behavior:

Don't pretend to be someone else, and don't represent that your product is authorized by, endorsed by, or produced by another company or organization, if that is not the case.

Developers should not divert users or provide links to any other site that mimics the Chrome Web Store or passes itself off as the Chrome Web Store. Your Product and its user experience also must not mimic functionality or warnings from a user's operating system or browser.

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

We do not allow products that deceive or mislead users, including in the content, title, description, or screenshots.

Don't misrepresent the functionality of your product or include non-obvious functionality that doesn't serve the primary purpose of the product. Descriptions of your product must directly state the functionality so that users have a clear understanding of the product they are adding. For example, products should not contain:

  • Claimed functionalities that are not possible to implement (e.g. "Who has viewed your social media account") or which are not directly provided by the extension (e.g. file converters which only link to other file conversion services)
  • Any metadata that misrepresents the extension's or developer's current status or performance on the Chrome Web Store (e.g. "Editor's Choice" or "Number One")

If your product has a blank description field or is missing an icon or screenshots, it will be rejected. If any of your product's content, title, icon, description, or screenshots contains false or misleading information, we may remove it.

User data policy - disclosure policy

Corresponds to notification ID: Purple Lithium

The User Data Privacy policy is a broad category under which several other policies are gathered. All of these policies have to do with the handling and transmission of sensitive information about the user.

This policy applies to all extensions that collect user data. This particular section is to ensure that users are aware of what data is collected, and how it is collected, used, and shared.

Common reasons for removal/rejection

  • The extension is collecting user data but has not provided a privacy policy.
  • The privacy policy is not provided in the designated field—a common mistake here is providing the privacy policy in the description.
  • The privacy policy URL is not working.
  • The privacy policy is not accessible.
  • The privacy policy URL is not leading to privacy policy.
  • The privacy policy does not talk about user data collection, usage, handling or sharing.

How can you rectify this?

  • Add a valid, working and accessible link to your privacy policy in the designated field.
    • Visit the Chrome Web Store item listing for your extension to verify that a privacy policy link appears in the "Additional Information" box and that the link works as expected.
  • Ensure the privacy policy talks about data collection, usage, handling, and sharing.
  • If you have done the above but are still encountering review issues, contact developer support to request clarification or appeal the verdict.

Relevant policy

This section addresses extensions that are in violation of the following section of the Chrome Web Store developer program policies:

Personal or Sensitive User Data

  • If your extension is offering some functionality and also injecting ads, then either stop injecting ads or remove all other functionality besides ad injection.
  • Chrome does not support optional new tab pages. If you wish to provide some functionality and an optional new tab page, you should separate the new tab page into a standalone extension.
  • Don't offer another unrelated functionality in the extension's action icon.

Relevant policy

This section addresses extensions that are in violation of the following section of the Chrome Web Store developer program policies:

Extensions Quality Guidelines

Single Purpose:

An extension must have a single purpose that is narrow and easy-to-understand. Do not create an extension that requires users to accept bundles of unrelated functionality. If two pieces of functionality are clearly separate, they should be put into two different extensions, and users should have the ability to install and uninstall them separately.

Common violations include:

  • Functionality that displays product ratings and reviews, but also injects ads into web pages.
  • Toolbars that provide a broad array of functionality or entry points into services are better delivered as separate extensions, so that users can select the services they want.
  • Email notifiers combined with a news aggregator.
  • PDF converters which also aim to change a user's default search engine.

User data policy - prominent disclosure

Corresponds to notification ID: Purple Nickel

The User Data Privacy policy is a broad category under which several other policies are gathered. All of these policies have to do with the handling and transmission of sensitive information about the user.

This section of the policy aims to ensure that users are aware of the data that is being collected and that user consent is obtained before data collection. Be aware that extensions may only collect data in direct support of their single purpose. See the Limited Use of User Data policy for additional information.

Common reasons for removal/rejection

  • The extension is not prominently disclosing how the user data is being used.
  • User consent is not obtained before data collection

How can you rectify this?

  • Prominently disclose to the user what data is being collected and how it will be handled. This information must be provided in the extension's Privacy Policy and may be provided elsewhere.
  • Ensure data is collected only if the user consents to it.
    • Prominent disclosure of data collection in the extension's Chrome Web Store listing is sufficient.
    • Collecting data that is not prominently disclosed in the Chrome Web Store listing is allowed so long as this data collection is consistent with the extension's single purpose, the user is informed of the data collection before it begins, and the user consents to the data collection.
  • Consider providing the user with ways to opt out of data collection from within the extension's options page.
  • Consider providing users with an "offline mode" that only stores user data locally.

Relevant policy
