Lightbeam for Firefox README

This is an add-on for Firefox that helps to visualize sites that may be tracking you around the internet. The add-on is available from https://addons.mozilla.org/en-US/firefox/addon/lightbeam/.

Prerequisites

If you only want to see the demo, you don't need any of these; all you need is a modern browser.

Quick Start

First, install the Mozilla Add-on SDK if you haven't already, and activate it in a command line terminal.

cd addon-sdk
source bin/activate

Then, check out the Lightbeam repository and enter it (do this where you want the lightbeam directory, not in the addon-sdk directory):

git clone git://github.com/mozilla/lightbeam.git
cd lightbeam

Finally, run:

cfx run

This will start Firefox with a temporary profile that has Lightbeam installed. Just click on the Lightbeam icon at the bottom-right of the browser window to open the web front-end.

At this point, any changes you make to the web front-end simply require reloading the tab containing it. Changing the add-on, however, will require quitting Firefox and running cfx run again.

Software Used

The following software is bundled with the repository and doesn't need to be manually obtained.

Data Used

Contained within the repository is a JSON file listing all public trackers on the internet. It came with the TrackerBlock add-on.
