How does the Chrome Web Store review extensions?

Chrome Web Store review checks policy compliance with manual and automated systems, looks harder at broad permissions and can recheck later. What it means.

The Chrome Web Store reviews every submission, new or updated, with a mix of manual and automated systems, checking it against its developer program policies. Reviewers look harder at new developers, dangerous permissions and big code changes. Published extensions can also be re-reviewed later, so approval is not permanent.

What the review is for

Google's developer documentation describes the review as a check for compliance with its developer program policies. That is a policy check. It is not a promise that the code is free of bugs or that the publisher will never change behavior. Keep that distinction in mind when someone on your team says an extension is fine because it is in the store.

Our post on the myth that the official store means safe goes deeper on that point.

What lengthens or deepens a review

FactorWhat the documentation says
New developer or new extensionGets a closer look
Dangerous permission requestsGets a closer look
Significant code changesGets a closer look
Broad host permissionsReviews may take longer
Obfuscated codeDisallowed, because it complicates validation
Past rejection or warningReview times may be longer

On broad host patterns, the documentation names examples such as all_urls and star slash star patterns, and says reviewers must confirm each requested permission is actually necessary and used appropriately. It notes that access this wide can be used to collect a user's browsing history.

How long it takes

The page says most extensions are reviewed within a few days, though some take a few weeks. It advises contacting developer support if an item has been pending more than three weeks. Note that the page also says it was last updated in December 2021 and that enforcement practices may change, so treat these timings as indicative.

After publication

Published extensions are occasionally reviewed outside the normal submission process. Triggers include periodic review, violations found in a new submission, and user reports. The documented outcomes run from no action, to a warning with typically 7 to 30 days to fix, to immediate takedown for serious violations. For extreme issues such as malware, takedown can happen without notifying the developer.

What this means for your laptops

Use store review as one signal, not the decision. Pair it with your own checks.

  1. Read the permissions before approving. The permission warnings decoded post helps.
  2. Check who publishes it and whether the publisher changed recently.
  3. Prefer extensions that ask for access only on click or on specific sites. See site access: on click or all sites.
  4. Re-check after updates that add permissions.
  5. Keep an allowlist so a store listing alone never installs anything on a company laptop.

Safeguard note

Safeguard's Chrome and Edge extension is one of the browser surfaces it offers, along with a free scan at gold.safeguard.sh/scan. Safeguard does not replace store review.

Quick check

Does store approval mean an extension will never turn malicious?

No. The documentation says published extensions can be re-reviewed and removed later, which implies a clean review at submission is not a lasting guarantee.

Why do broad host permissions get more attention?

They can expose a user's browsing history and other web activity, so reviewers must confirm each permission is needed.
