# Containers: Test Pilot Experiment
## AKA ??

[![Available on Test Pilot](https://img.shields.io/badge/available_on-Test_Pilot-0996F8.svg)](https://testpilot.firefox.com/)

[Embedded Web Extension](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Embedded_WebExtensions) to experiment with [Containers](https://blog.mozilla.org/tanvi/2016/06/16/contextual-identities-on-the-web/) in [Firefox Test Pilot](https://testpilot.firefox.com/) to learn:

* Will a general Firefox audience understand the Containers feature?
* Is the UI as currently implemented in Nightly clear or discoverable?

## Requirements

* Firefox 50+

### Development Environment

Add-on development is better with [a particular  environment](https://developer.mozilla.org/en-US/Add-ons/Setting_up_extension_development_environment). One simple way to get that environment set up is to install the [DevPrefs add-on](https://addons.mozilla.org/en-US/firefox/addon/devprefs/). You can make a custom Firefox profile that includes the DevPrefs add-on, and use that profile when you run the code in this repository. 

1. Make a new profile by running `/path/to/firefox -P`, which launches the profile editor. "Create Profile" -- name it whatever you wish (e.g. 'addon_dev') and store it in the default location. It's probably best to deselect the option to "Use without asking," since you probably don't want to use this as your default profile.

2. Once you've created your profile, click "Start Firefox". A new instance of Firefox should launch. Go to Tools->Add-ons and search for "DevPrefs". Install it. Quit Firefox.

3. Now you have a new, vanilla Firefox profile with the DevPrefs add-on installed. You can use your new profile with the code in _this_ repository like so:


### Run with jpm

1. Clone this repo locally
2. `cd testpilot-containers`
3. `npm install`
4. `./node_modules/.bin/jpm run -p /Path/To/Firefox/Profiles/{junk}.addon_dev -b FirefoxDeveloperEdition`
