HTTPS Everywhere and Privacy Badger

Last modified May 15, 2018
Duration: 1 hour

Learning Objectives

Learners will:

  • Be able to explain how HTTPS If you've ever seen a web address spelled out as “”, you'll recognize the “http” bit of this term. HTTP (hypertext transfer protocol) is the way a web browser on your machine...Read more is different from HTTP.

  • Be able to explain the “third-party” in “third-party cookie.”

  • Install HTTPS Everywhere.

  • Understand that HTTPS Everywhere does not create HTTPS connections when the website does not offer HTTPS.

  • Install Privacy Badger.

  • Understand that Privacy Badger does block tracking, but should not be considered an “ad blocker.”


  • Learners have their computers with them.

  • Learners have a web browser The program you use to view web sites on the Internet. Firefox, Safari, Internet Explorer and Chrome are all web browsers. Mobile devices have a web browser app for the same purpose. (Firefox, Opera or Google Chrome) installed.

  • Learners understand what a web browser is (and do not confuse it with a search engine or the Internet itself).


Instructor: Learners
Lecture-style (one instructor to ten students or more)

This session is mostly a knowledge-share. You can have a one-to-many model for most of the session.

The installation process is only a few clicks, but some people may need to troubleshoot. During the installation portion, you can ask learners who were able to quickly install HTTPS Everywhere and Privacy Badger on their computers to help others who are having more trouble.


You might hit some misconceptions about these two tools.

Privacy Badger Is Not An Ad Blocker

Sometimes, Privacy Badger is discussed alongside ad blockers like Adblock Plus. However, be sure to highlight that Privacy Badger is not an ad blocker. Instead, it’s a tracker blocker. Privacy Badger blocks third parties that appear to be tracking you across the web, whether they’re ads or not. Similarly, Privacy Badger will only block ads if they appear to be tracking you nonconsensually. In this way, one of Privacy Badger’s goals is to encourage more responsible, transparent advertising that respects users’ privacy.

HTTPS Everywhere Doesn’t Encrypt To apply encryption technology to any sort of information or communication. This transforms the information or communication mathematically so that it seems meaningless, but can still be restored...Read more Everything

With HTTPS Everywhere, it’s tempting for people new to the tool to think that it creates HTTPS where there is none.  You can clear this up by explaining that it’s up to website administrators whether they offer HTTPS or not. (And, luckily, more and more are offering it every day!) When they turn on HTTPS, some websites don’t do it by default, only encrypt some content, or link to unencrypted pages. HTTPS Everywhere helps with these more complicated instances and makes sure that users get any HTTPS that would otherwise fall through the cracks.

Privacy Badger and HTTPS Everywhere Aren’t 100% Solutions

It’s worth making clear what threat model A way of narrowly thinking about the sorts of protection you want for your data. It's impossible to protect against every kind of trick or attacker, so you should concentrate on which people might...Read more Privacy Badger and HTTPS Everywhere is meant to address. Privacy Badger stops companies from compiling information on your browsing patterns — it only provides marginal protection from attackers who are trying to target you directly, like criminals, stalkers or governments. HTTPS Everywhere helps increase the level of encryption A process that takes a message and makes it unreadable except to a person who knows how to "decrypt" it back into a readable form. you use everyday, which does increase your protection against mass surveillance or someone spying on your web traffic, but it doesn’t encrypt all of your communications.

Think of them both as vitamins. They give most people improved protection on a daily basis, but if you’re suffering from a particularly serious attacker, you’ll need stronger medicine.

Internet Connectivity, and Other Installing Problems

Installing browser extensions is one of the simpler ways to install additional software, but it’s still not foolproof. You may want to check connectivity with the venue beforehand, and stagger when and how people are downloading. If you’re doing a survey or pre-event instructions, ask people what browser they use. You might even encourage advanced users to install the software before hand.

Lesson Content


Before leading installation of Privacy Badger and HTTPS Everywhere, it might be helpful to go over:

What is a browser, and why should I download these browser extensions?
Some examples of browsers are Firefox, Google Chrome, Safari, and Internet Explorer. Often, your computer comes with one already on it. The browser is how to connect to the Internet - you use it when you want to go to websites and browse the web. A lot of browsers have built-in security and privacy features. When you install these extensions, you are adding to those protections.

Who is EFF and why should I download their stuff?
The standard answer is along the lines of: The Electronic Frontier Foundation is a San Francisco-based nonprofit organization defending civil liberties in the digital world, including privacy, security, free speech, and innovation. Depending on your audience, you can tailor this to how it is relevant to them. You might explain your own experience with the organization, or issues EFF works on that are particularly relevant to you or your audience. (In the context of installing new software, emphasizing the non-profit, consumer-rights side of EFF’s work often helps.)

Downloading these two extensions is among the easiest digital security moves one can make. Once you install them, the extensions do most (if not all!) of the work for you to make sure that you are not tracked across the web and that you use a secure connection whenever possible.

What does Privacy Badger do?
Third-party tracking—that is, when advertisers and websites track your browsing activity across the web without your knowledge, control, or consent—is an alarmingly widespread practice in online advertising. Privacy Badger puts you back in control by spotting and then blocking third-party domains that seem to be tracking your browsing habits.

Unlike other tracker blockers, which maintain a big list of trackers, Privacy Badger determines what sites to block by observing behaviors that are unique to trackers. Although Privacy Badger blocks many ads in practice, it is more a privacy tool than a strict ad blocker. Privacy Badger encourages advertisers to treat users respectfully and anonymously rather than the industry status quo of online tracking. It does this by unblocking content from domains which respect EFF’s Do Not Track policy, which states that the participating site will not retain any information about users who have expressed that they do not want to be tracked. You can always click on the extension to see which sites are being detected and blocked, and change what is being blocked if you want to.

What does HTTPS Everywhere do?
A collaboration between EFF and the Tor Project, HTTPS Everywhere is an extension for Firefox (both desktop and Android), Chrome, and Opera that makes your browser use HTTPS to encrypt its communication with websites wherever possible. Some websites offer inconsistent support for HTTPS, use unencrypted HTTP as a default, or link from secure HTTPS pages to unencrypted HTTP pages. HTTPS Everywhere fixes these problems by rewriting requests to these sites to HTTPS, automatically activating encryption and HTTPS protection that might otherwise slip through the cracks.

To do this, HTTPS Everywhere maintains the largest list available of sites that support HTTPS, and is used by other software such as the Brave browser and Automatic HTTPS Rewrites. It is also included in the Tor browser, to ensure that your anonymous browsing is as secure as possible.

What is HTTPS, anyway?
There are two ways for a website to get to your browser: HTTP and HTTPS. The difference is that “S,” which stands for “secure.” Web pages that come to you over HTTP are vulnerable to eavesdropping, content injection, cookie and credentials stealing, targeted censorship, and other problems. HTTPS pages, however, come secure by default.

When you see “https” and a little green lock next to the web page address in the top of your browser, that means you are using a secure connection. You have probably seen this when shopping online or entering credit card information.

If someone is spying on the network and trying to see what websites users are visiting, an HTTP connection offers no protection. An HTTPS connection, on the other hand, hides which specific page on a website you navigate to--that is, everything “after the slash.” For example, if you are using HTTPS to connect to, an eavesdropper can only see “”. With HTTPS, an eavesdropper cannot see what part of a website you’re visiting.

ACTIVITY: Installation!

Have your participants navigate to and, and direct them to click on the button that corresponds to the browser(s) they use. At this point, some might need help identifying their browser. You can help with this and, as some people complete their own installation, you can ask them to circulate and help others too.
