Language: 繁體中文 Español Deutsch Italiano Русский

Over the last 16 months, as I've debated this issue around the world, every single time somebody has said to me, "I don't really worry about invasions of privacy because I don't have anything to hide." I always say the same thing to them. I get out a pen, I write down my email address. I say, "Here's my email address. What I want you to do when you get home is email me the passwords to all of your email accounts, not just the nice, respectable work one in your name, but all of them, because I want to be able to just troll through what it is you're doing online, read what I want to read and publish whatever I find interesting. After all, if you're not a bad person, if you're doing nothing wrong, you should have nothing to hide." Not a single person has taken me up on that offer.

The UKUSA Agreement is an agreement between the United Kingdom, United States, Australia, Canada, and New Zealand to cooperatively collect, analyze, and share intelligence. Members of this group, known as the Five Eyes, focus on gathering and analyzing intelligence from different parts of the world. While Five Eyes countries have agreed to not spy on each other as adversaries, leaks by Snowden have revealed that some Five Eyes members monitor each other’s citizens and share intelligence to avoid breaking domestic laws that prohibit them from spying on their own citizens. The Five Eyes alliance also cooperates with groups of third party countries to share intelligence (forming the Nine Eyes and Fourteen Eyes), however Five Eyes and third party countries can and do spy on each other.

Why is it not recommended to choose a US based service?

Services based in the United States are not recommended because of the country’s surveillance programs, use of National Security Letters (NSLs) and accompanying gag orders, which forbid the recipient from talking about the request. This combination allows the government to secretly force companies to grant complete access to customer data and transform the service into a tool of mass surveillance.

An example of this is Lavabit – a discontinued secure email service created by Ladar Levison. The FBI requested Snowden’s records after finding out that he used the service. Since Lavabit did not keep logs and email content was stored encrypted, the FBI served a subpoena (with a gag order) for the service’s SSL keys. Having the SSL keys would allow them to access communications (both metadata and unencrypted content) in real time for all of Lavabit’s customers, not just Snowden's.

Ultimately, Levison turned over the SSL keys and shut down the service at the same time. The US government then threatened Levison with arrest, saying that shutting down the service was a violation of the court order.

Tor Browser

Tor project Tor Browser is your choice if you need an extra layer of anonymity. It's a modified version of Firefox, it comes with pre-installed privacy add-ons, encryption and an advanced proxy.

Download: torproject.org

OS: Windows, macOS, Linux, iOS, Android, OpenBSD.

Mozilla Firefox

Firefox Firefox is fast, reliable, open source and respects your privacy. Don't forget to adjust the settings according to our recommendations: WebRTC and about:config and get the privacy add-ons.

Download: firefox.com

OS: Windows, macOS, Linux, Android, iOS, BSD.

Brave

Brave browser The new open source browser "Brave" automatically blocks ads and trackers, making it faster and safer than your current browser. Brave is based on Chromium.

Download: brave.com

OS: Windows, macOS, Linux, Android, iOS.

Your Browser sends information that makes you unique amongst millions of users and therefore easy to identify.

When you visit a web page, your browser voluntarily sends information about its configuration, such as available fonts, browser type, and add-ons. If this combination of information is unique, it may be possible to identify and track you without using cookies. EFF created a Tool called Panopticlick to test your browser to see how unique it is.

Test your Browser now

You need to find what most browsers are reporting, and then use those variables to bring your browser in the same population. This means having the same fonts, plugins, and extensions installed as the large installed base. You should have a spoofed user agent string to match what the large userbase has. You need have the same settings enabled and disabled, such as DNT and WebGL. You need your browser to look as common as everyone else. Disabling JavaScript, using Linux, or even the TBB, will make your browser stick out from the masses.

Modern web browsers have not been architected to assure personal web privacy. Rather than worrying about being fingerprinted, it seems more practical to use free software plugins like Privacy Badger, uBlock Origin and Disconnect. They not only respect your freedom, but your privacy also. You can get much further with these than trying to manipulate your browser's fingerprint.

WebRTC is a new communication protocol that relies on JavaScript that can leak your actual IP address from behind your VPN.

While software like NoScript prevents this, it's probably a good idea to block this protocol directly as well, just to be safe.

Test your Browser now

How to disable WebRTC in Firefox?

In short: Set "media.peerconnection.enabled" to "false" in "about:config".

Explained:

Enter "about:config" in the firefox address bar and press enter.
Press the button "I'll be careful, I promise!"
Search for "media.peerconnection.enabled"
Double click the entry, the column "Value" should now be "false"
Done. Do the WebRTC leak test again.

If you want to make sure every single WebRTC related setting is really disabled change these settings:

media.peerconnection.turn.disable = true
media.peerconnection.use_document_iceservers = false
media.peerconnection.video.enabled = false
media.peerconnection.identity.timeout = 1

Now you can be 100% sure WebRTC is disabled.

Test your Browser again

How to fix the WebRTC Leak in Google Chrome?

WebRTC cannot be fully disabled in Chrome, however it is possible to change its routing settings (and prevent leaks) using an extension. Two open source solutions include WebRTC Leak Prevent (options may need to be changed depending on the scenario), and uBlock Origin (select "Prevent WebRTC from leaking local IP addresses" in Settings).

What about other browsers?

Chrome on iOS, Internet Explorer and Safari does not implement WebRTC yet. But we recommend using Firefox on all devices.

Improve your privacy with these excellent Firefox add-ons.

Stop Tracking with "Privacy Badger"

Privacy Badger is a browser add-on that stops advertisers and other third-party trackers from secretly tracking where you go and what pages you look at on the web. Privacy Badger learns about trackers as you browse by inspecting external resources websites request. Please be aware that Google Analytics is considered first-party by Privacy Badger, which means that Google Analytics will not be blocked if you do not use another blocker, such as uBlock Origin. https://www.eff.org/privacybadger/

Block Ads and Trackers with "uBlock Origin"

An efficient wide-spectrum-blocker that's easy on memory, and yet can load and enforce thousands more filters than other popular blockers out there. It has no monetization strategy and is completely open source. We recommend Firefox but uBlock Origin also works in other browsers such as Safari, Opera, and Chromium. Unlike AdBlock Plus, uBlock does not allow so-called "acceptable ads".
https://addons.mozilla.org/firefox/addon/ublock-origin/

Automatically Delete Cookies with "Cookie AutoDelete"

Automatically removes cookies when they are no longer used by open browser tabs. With the cookies, lingering sessions, as well as information used to spy on you, will be expunged.
https://addons.mozilla.org/firefox/addon/cookie-autodelete/

Encryption with "HTTPS Everywhere"

A Firefox, Chrome, and Opera extension that encrypts your communications with many major websites, making your browsing more secure. A collaboration between The Tor Project and the Electronic Frontier Foundation.
https://www.eff.org/https-everywhere

Block Content Delivery Networks with "Decentraleyes"

Emulates Content Delivery Networks locally by intercepting requests, finding the required resource and injecting it into the environment. This all happens instantaneously, automatically, and no prior configuration is required. Source code: GitLab (self-hosted).
https://addons.mozilla.org/firefox/addon/decentraleyes/

The following add-ons require quite a lot of interaction from user to get things working. Some sites will not work properly until you have configured the add-ons.

Stop cross-site requests with "uMatrix"

Many websites integrate features which let other websites track you, such as Facebook Like Buttons or Google Analytics. uMatrix gives you control over the requests that websites make to other websites. This gives you greater and more fine grained control over the information that you leak online.
https://addons.mozilla.org/firefox/addon/umatrix/

Be in total control with "NoScript Security Suite"

Highly customizable plugin to selectively allow Javascript, Java, and Flash to run only on websites you trust. Not for casual users, it requires technical knowledge to configure.

This is a collection of privacy related about:config tweaks. We'll show you how to enhance the privacy of your Firefox browser.

Preparation:

Enter "about:config" in the firefox address bar and press enter.
Press the button "I'll be careful, I promise!"
Follow the instructions below...

Getting started:

privacy.firstparty.isolate = true
- A result of the Tor Uplift effort, this preference isolates all browser identifier sources (e.g. cookies) to the first party domain, with the goal of preventing tracking across different domains. (Don't do this if you are using the Firefox Addon "Cookie AutoDelete" with Firefox v58 or below.)
privacy.resistFingerprinting = true
- A result of the Tor Uplift effort, this preference makes Firefox more resistant to browser fingerprinting.
privacy.trackingprotection.enabled = true
- This is Mozilla’s new built in tracking protection. It uses Disconnect.me filter list, which is redundant if you are already using uBlock Origin 3rd party filters, therefore you should set it to false if you are using the add-on functionalities.
browser.cache.offline.enable = false
- Disables offline cache.
browser.safebrowsing.malware.enabled = false
- Disable Google Safe Browsing malware checks. Security risk, but privacy improvement.
browser.safebrowsing.phishing.enabled = false
- Disable Google Safe Browsing and phishing protection. Security risk, but privacy improvement.
browser.send_pings = false
- The attribute would be useful for letting websites track visitors’ clicks.
browser.sessionstore.max_tabs_undo = 0
- Even with Firefox set to not remember history, your closed tabs are stored temporarily at Menu -> History -> Recently Closed Tabs.
browser.urlbar.speculativeConnect.enabled = false
- Disable preloading of autocomplete URLs. Firefox preloads URLs that autocomplete when a user types into the address bar, which is a concern if URLs are suggested that the user does not want to connect to. Source
dom.battery.enabled = false
- Website owners can track the battery status of your device. Source
dom.event.clipboardevents.enabled = false
- Disable that websites can get notifications if you copy, paste, or cut something from a web page, and it lets them know which part of the page had been selected.
geo.enabled = false
- Disables geolocation.
media.eme.enabled = false
- Disables playback of DRM-controlled HTML5 content, which, if enabled, automatically downloads the Widevine Content Decryption Module provided by Google Inc. Details
- DRM-controlled content that requires the Adobe Flash or Microsoft Silverlight NPAPI plugins will still play, if installed and enabled in Firefox.
media.gmp-widevinecdm.enabled = false
- Disables the Widevine Content Decryption Module provided by Google Inc., used for the playback of DRM-controlled HTML5 content. Details
media.navigator.enabled = false
- Websites can track the microphone and camera status of your device.
network.cookie.cookieBehavior = 1
- Disable cookies
- 0 = Accept all cookies by default
- 1 = Only accept from the originating site (block third party cookies)
- 2 = Block all cookies by default
network.cookie.lifetimePolicy = 2
- cookies are deleted at the end of the session
- 0 = Accept cookies normally
- 1 = Prompt for each cookie
- 2 = Accept for current session only
- 3 = Accept for N days
network.http.referer.trimmingPolicy = 2
- Send only the scheme, host, and port in the Referer header
- 0 = Send the full URL in the Referer header
- 1 = Send the URL without its query string in the Referer header
- 2 = Send only the scheme, host, and port in the Referer header
network.http.referer.XOriginPolicy = 2
- Only send Referer header when the full hostnames match. (Note: if you notice significant breakage, you might try 1 combined with an XOriginTrimmingPolicy tweak below.) Source
- 0 = Send Referer in all cases
- 1 = Send Referer to same eTLD sites
- 2 = Send Referer only when the full hostnames match
network.http.referer.XOriginTrimmingPolicy = 2
- When sending Referer across origins, only send scheme, host, and port in the Referer header of cross-origin requests. Source
- 0 = Send full url in Referer
- 1 = Send url without query string in Referer
- 2 = Only send scheme, host, and port in Referer
webgl.disabled = true
- WebGL is a potential security risk. Source
browser.sessionstore.privacy_level = 2
- This preference controls when to store extra information about a session: contents of forms, scrollbar positions, cookies, and POST data. Details
- 0 = Store extra session data for any site. (Default starting with Firefox 4.)
- 1 = Store extra session data for unencrypted (non-HTTPS) sites only. (Default before Firefox 4.)
- 2 = Never store extra session data.
network.IDN_show_punycode = true
- Not rendering IDNs as their punycode equivalent leaves you open to phishing attacks that can be very difficult to notice. Source

Who is required to hand over the encryption keys to authorities?

Mandatory key disclosure laws require individuals to turn over encryption keys to law enforcement conducting a criminal investigation. How these laws are implemented (who may be legally compelled to assist) vary from nation to nation, but a warrant is generally required. Defenses against key disclosure laws include steganography and encrypting data in a way that provides plausible deniability.

Steganography involves hiding sensitive information (which may be encrypted) inside of ordinary data (for example, encrypting an image file and then hiding it in an audio file). With plausible deniability, data is encrypted in a way that prevents an adversary from being able to prove that the information they are after exists (for example, one password may decrypt benign data and another password, used on the same file, could decrypt sensitive data).

Edward Snowden on reddit

The NSA has built an infrastructure that allows it to intercept almost everything. With this capability, the vast majority of human communications are automatically ingested without targeting. If I wanted to see your emails or your wife's phone, all I have to do is use intercepts. I can get your emails, passwords, phone records, credit cards. I don't want to live in a society that does these sort of things... I do not want to live in a world where everything I do and say is recorded. That is not something I am willing to support or live under.

Edward Snowden in The Guardian

We all need places where we can go to explore without the judgmental eyes of other people being cast upon us, only in a realm where we’re not being watched can we really test the limits of who we want to be. It’s really in the private realm where dissent, creativity and personal exploration lie.
