MetaMask Flask is a distribution channel of the MetaMask extension for developers that gives them access to additional unstable APIs. The goal of Flask is to maximize developer control, so that we can learn the full extent of what developers want to do with MetaMask, and later incorporate those lessons into the main MetaMask distribution.

You can find the main / production version of MetaMask here:
https://addons.mozilla.org/en-US/firefox/addon/ether-metamask/

This is the first release of MetaMask Flask on Firefox. For an introduction to Flask, see https://metamask.io/flask. For a history of versions and changes, see https://github.com/MetaMask/metamask-extension/releases.
