After configuring Mozilla Firefox according to this guide it's rating changes like so:
</p>
<h3>Spyware Rating: <font color="orange">High</font> =&gt; <font color="lime">Not Spyware</font></h3>
<p>
Before beginning this guide it is important that you try and cross-reference it with other guides,
to see which prespective on this topic is the best way to do it for you. At the bottom of the page are links
to <a href="#Other_Guides">other guides</a> and projects like this one. You should strongly consider this as <b><font color=orange>
you may find other guides more useful than this one.</font></b>
Mozilla Firefox is one of the most popular and longest existing
browsers. Its developers have earned it a reputation for being a "privacy and security-based browser, respecting the user" - but is it justified, or just marketing? In fact, over the years they have made several anti-privacy (and generally anti-user) decisions, but this article will focus exclusively on spying. Version tested: 52.5.0, with the default settings. Program used for testing requests: Mitmproxy.
</p>
<p>
Mozilla Firefox has a huge amount of spyware features, but they all can be disabled by using predefined profile settings.
To do this you need to create new Firefox profile:
<ul>
<li> Run <code>firefox -no-remote -ProfileManager</code> </li>
<li> Create a new profile </li>
<li> Exit. </li>
</ul>
Then open your Firefox user profiles directory. It should be located at:
<h2>Spyware Level: <font color=orange>High</font></h2>
After following the <a href="../guides/firefox.html">mitigation guide</a>, this software is <font color=lime><b>Not Spyware</b></font>.
</p>
<p>It sends a lot of different data very often (some of which could
uniquely identify you). All the "services" that it provides, such as
its default search engines and Pocket, are anti-privacy. The rating isn't higher
because at least you can turn off or modify most of it, though
it often requires diving deep into about:config.</p>
<table border background="../images/bg.jpg" style="width:800px">
<h3>Phoning home</h3>
<p>
Whenever you start Firefox, it makes this request: <br><img src="../images/request.png"><br> In fact, it makes it every time you go to a website, and even a few times in a row for a single website. So Firefox "phones home" all the time, without your knowledge. <b><font color=orange>Can be disabled ONLY in about:config</font></b>. But, since you've already started Firefox, it will make this request at least once.
</p>
<h3>Automatic connections to some websites you've visited, including their trackers</h3>
<p>
Websites you visit most often are added to the New Tab panel. When you then open a new tab, Firefox will sometimes make requests to the sites in there, including some of their trackers. I haven't determined how it works yet. Sometimes it doesn't make the requests at all; other times you end up with hundreds of images, scripts, trackers, etc. loaded simply because you opened a new tab (without visiting any website explicitly).
<b><font color=red>Was NOT able to find a way to disable this</font></b>, even in about:config.
</p>
<h3>Firefox tracks users with Google Analytics</h3>
<p>
Firefox has been integrated with the spyware platform called "Google Analytics"<sup><a href="#1">[1]</a></sup>. Firefox has been confirmed to now send analytics to Google. According to a Firefox developer the spyware in Firefox is "extremely useful to us and we have already weighed the cost/benefit of using tracking." and that Firefox will not remove Google Analytics support entirely. Firefox's position on privacy is made very clear with this quote:
</p>
<p><i>"Wanted to address your position though:
We don't give the "data directly to Google". See the discussion here: https://bugzilla.mozilla.org/show_bug.cgi?id=858839. The short version is:
tl;dr: We now have an option to opt-out of Google doing anything with the data that Google Analytics collections on Mozilla websites. GA tracking is anonymous and at the aggregate level and we use it to improve the experience of our websites.
We are collecting aggregate and non-identifiable data in numbers to ensure our development/UX changes are met well. We can respect privacy and still have analytics; in fact Mozilla's aim is for an experience that values user privacy and usability (I'd say Apple also wants UX that fits that mold, as an example). We need some data, anonymised and aggregated, to do this.
"</i></p>
<p>
The best takeaway to this is that Mozilla wants to pretend that including spyware in their program is somehow not a breach of privacy, and that Firefox could possibly be respecting user privacy while simultaneously collecting data on users and sending it to Google. It's strongly suggested to read the github thread and the further anti-privacy statements the Mozzilla employee makes while defending the spyware features in Firefox. It's very dangerous to assert that there is somehow a middle ground between respecting user privacy and datamining the user.
</p>
<h3>"Safe" Browsing?</h3>
<p>
Allegedly used to protect you from "phishing" websites, but in the end, it makes a bunch of requests to Google every 30 minutes (according to Mozilla), including a POST request with your Firefox version and a unique, persistent, hidden cookie. Since whenever the current URL matches an entry in the cached local blacklist a request is made to Google servers, ostensibly to test whether that website is still on the master online blacklist, it allows Google to monitor specific websites transparently to the user by putting the URLs of interest on the local but not the online blacklist. <br><img src="../images/safe_browsing.png"><b><font color=orange>Can be disabled ONLY in about:config.</font></b>
</p>
<h3>Firefox Health Report</h3>
<p>
From the horse's mouth: "For example, FHR sends data to Mozilla on things like: operating system, PC/Mac, number of processors, Firefox version, the number and type of add-ons. The data collected by FHR is tied to a Document ID that corresponds to a browser installation (explained above in question #4) so that the data can be correlated across a limited window of time."<sup><a href="#2">[2]</a></sup> Also, according to Mozilla, new versions of Firefox will also collect telemetry data by default. <b><font color=lime>Can be disabled through the GUI.</font></b>
</p>
<h3>Anti-privacy search engines by default</h3>
<p>Old versions of Firefox had Google as the default search engine,
which is obviously anti-privacy. For example, from their privacy
policy: "When you use our
services or view content provided by Google, we automatically collect
and store certain information in server logs. This includes: details
of how you used our service, such as your search queries.". Then, it
was Yahoo, which isn't better: "The Yahoo Search History tool allows
you to see what you've searched for in the past. ". So it saves all
your searches. And deleting does nothing: "Even if you clear your
past searches or turn the Search History tool off, Yahoo still
collects and stores search user log data when you use Yahoo Search
technology." Firefox 57 is going back to Google again. If they really
cared about your privacy, the default search engine would be
StartPage (which gives the same results as Google, but anonymized) or
DuckDuckGo. <b><font color=lime>Can be changed through the GUI.</font></b>
</p>
<h3>Pocket - a privacy nightmare</h3>
<p>
Firefox has a Pocket button in its navigation bar, which allows you
to "save any article, video or page from Firefox" and "View in Pocket
on any device, any time." Let's see how it looks in terms of privacy
- quoting from Pocket's privacy policy<sup><a href="#3">[3]</a></sup>:
"In addition to the information that you provide to us when you
register for a user account, we collect information about the URLs,
titles and content of the web pages and other information you save to
Pocket." So everything you conveniently put in "your" Pocket is
being stored (of course, otherwise Pocket wouldn't work). "The types
of information we collect includes your browser type, device type,
device id, time zone, language, and other information related to the
manner in which you access the Pocket Technologies. " So anytime you
view a file in "your" Pocket, they know everything about the device
you used to do it. "We may also use "pixel tags," "web beacons,"
"clear GIFs" or similar means (individually or collectively "Pixel
Tags") in connection with emails that we send to our users in order
to collect usage data." So, they are acting like any old tracking
website, even in ways that have nothing to do with their
functionality. "We may also share your device ID with third parties
in connection with advertising campaigns. " And they work with
advertisers too! Describing all of Pocket's
violations would take up this whole article. There are similar services with better privacy policies, but in the end, they still store the things you view in "the cloud". A real privacy-based browser would not be integrated with them by default.
</p>
<font color=yellow> <b>Can be disabled in about:config</b></font><sup><a href="#8">[8]</a></sup>
<h3>Automatic updates</h3>
<p>
Not that bad compared to all of the above, I guess - but still
installs something without your consent, with possible new privacy
nightmares in there. There is no excuse to at least not make "Check for updates, but
let me choose whether to install them" the default - it would still
give the security benefit, but not take control away from the user.
<b><font color=lime>Can be disabled through the GUI.</font></b>
</p>
<h3>Other issues</h3>
<p>
Firefox also sometimes makes a request to "self-repair.mozilla.org" which looks like this:
<br><img src="../images/self_repair.png">
It includes "optimizelyEndUserID" which probably means it
<b>uniquely identifies you. </b><b><font color=orange>Can be disabled ONLY in about:config.</font></b><sup><a href="#7">[7]</a></sup><br>
It also makes this request every time you open the default home page:
<img src =../images/request2.png"><br>
The number after the Firefox version is, again, <b>uniquely
identifying</b><sup><a href="#4">[4]</a></sup><b><font color=orange> Can be disabled ONLY in about:config.</font></b>
<br>
Firefox has a file with list of blocked addons that it considers "malicious" and it makes a request to update it every day (even if you don't have any addons installed). <img src =../images/blocklist.png"> The request includes a <b>uniquely identifying</b> browser installation ID. <b><font color=orange>Can be disabled ONLY in about:config.</font></b>
</p>
<h3>Firefox phones home about almost every single interaction you have with its UI</h3>
<p>
Firefox will send information about almost every basic operation that you do back to Mozilla. This is tagged with a unique client ID and an ID for your current session, and any relevant information related to this action.
<b><font color=red>By default, the following uses of the UI are reported to Mozilla<sup><a href="#5">[5]</a></sup>:</font></b>
<ul>
<li>Performing a search</li>
<li>Clicking a top site item</li>
<li>Deleting an item from history</li>
<li>Blocking a site</li>
<li>Bookmarking a link</li>
<li>Removing a bookmark from a link</li>
<li>Opening a link in a new window</li>
<li>Opening a link in a new private window</li>
<li>Opening the new tab preferences pane</li>
<li>Closing the new tab preferences pane</li>
<li>Acknowledging a section disclaimer</li>
<li>Adding or editing a new TopSite</li>
<li>Requesting a custom screenshot preview</li>
<li>Session end</li>
<li>Impression stats</li>
<li>Click/block/save_to_pocket ping</li>
<li>Addon initialization failure</li>
<li>Domain affinity calculation</li>
</ul>
<p>
Essentially, while this feature doesn't broadcast your search history to Mozilla, it proives an incedibly detailed walktrhough of exactly how you use Firefox's user interface. This can be disabled and is an opt-out spyware feature. You can disable it through the GUI as described here:
<a href="https://support.mozilla.org/en-US/kb/share-data-mozilla-help-improve-firefox">Share data with Mozilla to help improve Firefox</a>

<h3>Mitigating Firefox Spyware</h3>
<p>
This reveiew is also accompanied by a page about how to configure Firefox to be more privacy respecting, and links to other projects that have been created to solve this
problem. You can read about that <a href="/guides/firefox.html">here.</a> These are some of the flags in about:config mentioned earlier in the article, and the values that
they should be set too:
</p>

<p>
Delete everything from the new profile and get ghack's user.js<br>
<ul><li>cd /path/to/your/profile && rm -r * && wget https://raw.githubusercontent.com/ghacksuserjs/ghacks-user.js/master/user.js</li></ul>
You may want to edit the file to your needs, if so
<ul><li>yourtexteditor user.js</li></ul>
</p>
<p>
If you want to disable OCSP as well, you should also add this to your user.js. These settings are seperated
because while OCSP is a privacy breach it is also a security feature, and so whether to have it on or off should
be thought about before continuing. You can read about OCSP here: <a href="https://scotthelme.co.uk/revocation-is-broken/">
https://scotthelme.co.uk/revocation-is-broken/</a> <a href="http://web.archive.org/web/20180831224302/https://scotthelme.co.uk/revocation-is-broken/">
[web.archive.org]</a> . The problem is, that OCSP is a form of phoning home, and you might not want to make those requests.
</p>
<code>
user_pref("security.ssl.enable_ocsp_stapling", false);<br>
user_pref("security.OCSP.enabled", 0);<br>
user_pref("security.OCSP.require", false);<br>
</code>
<p>
With this installation method, if you change any of user.js settings through about:config or Firefox preferences dialogs,
they will be reset to the user.js defined values after you restart Firefox.
This makes sure they're always back to secure defaults when starting the browser.
At the end you need to delete several default plugins in Firefox directory at <code>\Mozilla Firefox\browser\features\</code> that can violate privacy:
</p>
<ul>
<li> firefox@getpocket.com.xpi - Pocket </li>
<li> followonsearch@mozilla.com.xpi - Follow On Search </li>
<li> activity-stream@mozilla.org.xpi - Activity Stream </li>
<li> screenshots@mozilla.org.xpi - Screenshots </li>
<li> onboarding@mozilla.org.xpi - Onboarding </li>
<li> formautofill@mozilla.org.xpi - Autofill </li>
<li> webcompat@mozilla.org.xpi - Web Compatibility Reporter </li>
</ul>
<p>
It is highly recommended to also check other user.js template settings from ongoing <i>"ghacks-user.js project"</i><sup><a href="#1">[1]</a></sup> for further hardening Firefox privacy, security and anti-fingerprinting.

<h2>Other Guides</h2>
<h2>Further Reading</h2>
<p>
These are other guides and projects to help protect your privacy using Firefox. It's important to look at
other prespectives instead of reading JUST this guide. So you should be comparing all of the
guides that you can find to hear everyone's ideas about how this should be done, before you
finish setting Firefox up. Librefox is less of a guide and more of a project and series of tools and settings
you can download to help you make Firefox private.
