Injects your Polkadot accounts from Parity Signer and allows signing transactions

What is Parity Signer Companion?

Parity Signer Companion is a Firefox add-on that enables users to inject and sign transactions using their Polkadot accounts stored in Parity Signer, a secure key storage solution. It works seamlessly with the Signer but requires its presence to operate. For key creation and storage without any device, consider using the Polkadot{.js} extension.
