A percentage of shareholders, usually 67% to 90%. A supermajority is often required for a company to take certain actions, such as amending the charter.

A certificate authority can issue multiple certificates in the form of a tree structure. A root certificate is the top-most certificate of the tree, the private key of which is used to sign other certificates. All certificates signed by the root certificate, with the CA field set to true, inherit the trustworthiness of the root certificateâa signature by a root certificate is somewhat analogous to notarizing an identity in the physical world.
Mozilla will consider removing a root certificate from NSS if the CA is issuing certificates in a manner that is non-compliant with Mozilla's CA Certificate Policy. (As per the previous point, a CA that is issuing certificates that are being used in MitM attacks is non-compliant with Mozilla's CA Certificate Policy.)
