The extension makes API calls from the popup to our domain. We are a subscription service and expect auth-cookie to be sent along with API requests from the extension. Our auth cookies are SameSite=Lax. Chrome and Firefox allow SameSite=Lax cookie to be sent with API calls from the extension, but Safari does not. The expected behavior is: SameSite: Lax cookies should follow the behavior as extension in Chrome and Firefox. 1700828 1 smoley 2020-10-22 14:07:03 -0700 Thanks for filing.
