Hello everyone,

On the Chrome Web Store, there is now a universal limit of 75 characters for an extension's name field in their manifest.json.

Up until yesterday, the limit for english was 45 characters, and there was no restriction to the name field used in other locales.

This was originally intended to allow for cultural and language differences that may not be able to be captured in the same amount of characters. Unfortunately, this feature was abused by a small number of developers to spam the store. As a result we are introducing a new universal limit, an increase to 75 characters. This limit covers nearly all extensions on the store today, so it is likely no action will be needed by you as a result of this change.

If you try to upload an extension that has a name longer than the maximum limit, then the upload will be blocked by the store.

You would need to update the extension to lower the localized fields to at or below the allowable limit.

If you have an existing extension that has a name field longer than the allowed limit, it will not be proactively removed from the store. You will need to update the localization files to be compliant before you can publish a new version.
