Oops! We've accidentally introduced an auth bug in version 3.1.5. This version is now disabled and we advise updating to the latest version. Our apologies!

The extension does not require a sign-up. You can use it without an API token. The API token field is for people with an active subscription. The free trial is for our API product and shouldn’t be used in the extension; the extension works without an API account and is completely free.
