Sparrow by Julian Yap

Sparrow creates endless possibilities within the Ubiq network by providing access to Dapps within your Firefox browser.

The extension injects the Ubiq web3 API into every website's javascript context, so that dapps can read from the blockchain.

Sparrow also lets the user create and manage their own identities (via private keys, local client wallet and hardware wallets like Trezor™), so when a Dapp wants to perform a transaction and write to the blockchain, the user gets a secure interface to review the transaction, before approving or rejecting it.

Because it adds functionality to the normal browser context, Sparrow requires the permission to read and write to any webpage. You can always "view the source" of Sparrow the way you do any Firefox extension, or view the source code on Github:
