If relevant Mozilla people are here: Send does not work if "Delete cookies and site data when Firefox closes" checkbox in FF preferences is checked. Even the page doesn't load [1]. It surely is a bug, because I am not closing Firefox.
That checkbox is #1 reason I only use Firefox.

SecurityError: The operation is insecure."
