INACTIVE - http://mzl.la/ghe-archive - Shield Study Add-on to experiment with various Firefox privacy preference values.

Privacy Prefs

Purpose

Firefox contains a number of about:config preferences that can improve user privacy. E.g.,

• https://github.com/fmarier/user.js/blob/SeaGL/user.js
• securefox ideas etherpad
• Referrer Improvements ideas etherpad

This Shield Study add-on sets these preferences to non-default values, so we can measure user feedback and their effect on Firefox usage.

General Setup and Install

1. Install shield and jpm: npm install -g shield-study-cli jpm
2. Clone this repo and change to its directory
3. npm install
4. shield run . -- -b Aurora

privacy-prefs's Issues

Set up variations for features that can be disabled without much breakage

See https://github.com/fmarier/user.js/blob/SeaGL/user.js ...

user_pref("beacon.enabled", false);
user_pref("device.sensors.enabled", false);
user_pref("dom.battery.enabled", false);
user_pref("geo.enabled", false);
user_pref("media.eme.enabled", false); // proprietary DRM plugins
user_pref("dom.netinfo.enabled", false);
user_pref("pdfjs.disabled", true); // use external PDF viewer instead
user_pref("layout.css.visited_links_enabled", false); // regularly leaks
user_pref("media.video_stats.enabled", false);
user_pref("browser.casting.enabled", false); // https://bugzil.la/1111967

CODE_OF_CONDUCT.md file missing

As of January 1 2019, Mozilla requires that all GitHub projects include this CODE_OF_CONDUCT.md file in the project root. The file has two parts:

1. Required Text - All text under the headings Community Participation Guidelines and How to Report, are required, and should not be altered.
2. Optional Text - The Project Specific Etiquette heading provides a space to speak more specifically about ways people can work effectively and inclusively together. Some examples of those can be found on the Firefox Debugger project, and Common Voice. (The optional part is commented out in the raw template file, and will not be visible until you modify and uncomment that part.)

If you have any questions about this file, or Code of Conduct policies and procedures, please see Mozilla-GitHub-Standards or email [email protected].

Wiki changes

FYI: The following changes were made to this repository's wiki:

• defacing spam has been removed

• Restricting write access to contributors is strongly encouraged. Please make that change (documentation).

These were made as the result of a recent automated defacement of publically writeable wikis.
