Out of the box, Mozilla Firefox’s open-source browser has more privacy functions than most other mainstream options. While a few of the default settings are powerful bastions against malicious cyber activity, the majority of this safety stems from settings—and as with any kind of software, you can improve the functionality by changing and modifying these settings.

There are add-ons galore that affect yourFirefox experience. We’ll get into those later in the article, but for now,let’s start with the basics: the simplest steps you can take to improve Firefox’ssecurity.

1. Set up a Master Password

Open any modern browser and you’ll be giventhe option to save your username and password when you log into a website. Thisis a small convenience that most take for granted, but it’s also a majorsecurity flaw. Anyone that uses your computer will have access to your accountsjust by visiting that website.

Firefox solves this problem with the masterpassword option. When enabled, this forces the user to enter the masterpassword before any saved information can be used. In addition, if you want toview the saved passwords via the options menu you will need to enter the masterpassword again.

Your master password has to be secure. Makesure you do not save it on your computer, but instead write it down somewherein your home or use memorization techniques to track it. Use best practices forpassword creation when making it.

2. Make Sure Privacy Settings are Enabled.

After you install Firefox, make sure thevarious privacy and security settings are enabled. Go to the Firefox Menu, thento Preferences, and then select General. Scroll down to the “FirefoxUpdates” section. Select “Automatically install updates.”

Next, choose the “Privacy andSecurity” tab. The first section you will see is “ContentBlocking.” By default, Firefox is set to the “Standard”option—to only block known trackers in Private Windows. Switch this to“Strict,” but be aware that some websites might not operate properlywith this chosen.

Below that, choose “Always” for the“Do not track” option.

Scroll down to the “Permissions”section. You’ll see several options. Make sure the following are checked:

  • “Block websites fromautomatically playing sound.”
  • “Block pop-upwindows.”
  • “Warn you when websitestry to install add-ons.”
  • “Prevent accessibilityservices from accessing your browser.”

Anote on accessibility services: if you require these services to effectivelybrowse the Internet and use your computer, make sure you research and know whatservices you can trust. Some malicious software can use these services to gainaccess to your browser, and via that, to your computer.

Next, scroll down to the“Security” tab. You’ll see several boxes. Make sure they are allchecked.

  • “Block dangerous anddeceptive content.”
  • “Block dangerousdownloads.”
  • “Warn you about unwantedand uncommon software.”

Add-Ons for Safety and Privacy

Add-ons are the Firefox equivalent to Chrome’s extensions. These applications give users the ability to customize their browser to their hearts’ content and implement security features that no other browsers come close to matching.

Of course, not all add-ons are created equal. We’ve compiled a list of the best options that have a positive effect on the overall privacy and security of Firefox.

HTTPSEverywhere

HTTPS Everywhere is a favorite add-onbecause of how simple it is. In layman’s terms, it enables secure browsing onany website that supports it. In more technical terms, it provides three layersof security: server authentication, data confidentiality, and data integrity.Should anyone intercept data transmitted through HTTPS Everywhere, they wouldbe unable to interpret it without the encryption key.

uBlockOrigin

No one likes annoying pop-up adds, especially when some of them have the ability to pull personal information from your browser. While Firefox has a suite of built-in tools to stop pop-ups, it doesn’t catch them all.

uBlock Origin is a free, open-source ad blocker that can handle anything that Firefox misses. It’s also customizable, so if there is a specific page you want to allow ads on (to support the creator, perhaps) then you can whitelist that individual page.

PrivacyBadger

Privacy Badger is another add-on developedby the Electronics Frontier Foundation, the same team behind HTTPS Everywhere. Manyanti-tracking tools keep a list of misbehaving websites, but Privacy Badgermonitors your browsing experience in real time and watches what domains trackyou. If any of these domains violate your privacy and security settings, thenPrivacy Badger will automatically block them.

PrivacyPossum

Redundant security is always a good thing. While most trackers will be caught by Firefox’s built-in anti-tracking tools and Privacy Badger, Privacy Possum makes sure than any that slip through the cracks gather nothing more than falsified, scrambled data.

With both add-ons installed, you don’t have to worry about companies finding out more about you than you want them to, at least from your browsing habits.

CookieAutoDelete

This add-on is about as straightforward asit gets. When you close Firefox, any cookies not actively in use areautomatically deleted. You can whitelist specific cookies that you want tokeep, but any others will vanish. It’s a great protective measure againstwebsites trying to pull data you haven’t given permission to take.

Disconnectfor Facebook

Facebook is a force of nature. How many websites can you think of that track your Facebook account? How many times have you been given the ability to comment because you were already logged into Facebook? If this bothers you (as it should), then the add-on Disconnect for Facebook will help.

This add-on blocks requests for Facebook information from third-party websites. It will also block traffic from third-party websites to Facebook, but does not interfere with the standard operation of your Facebook account.

How to Install Add-ons to Firefox

You do not have to use all of theseadd-ons, but we do recommend at least installing Privacy Badger, HTTPSEverywhere, and uBlock Origin. There are hundreds of other add-ons you canbrowse and install if you want even more options than we have listed out here.

Installing an add-on is not complicated. Here’show.

1. Open Firefox and click the three bars onthe far-right side to open the settings menu.

2. Click “Add-ons.”

3. This opens automatically to the Get Add-ons tab. Click “Find more add-ons.”

4. A new tab will open. In the search barin the top-right corner, type in the name of the add-on you want.

5. Click the add-on in the search results.

6. On the next page, click the button that says “Add to Firefox.”

7. The browser will request permission to installthe add-on. Click yes.

8. Voila! You now have the add-on yousearched for. Rinse and repeat for the rest.

A Final Note on Cybersecurity

You might think to yourself, “Why isall of this necessary? Hackers aren’t interested in me.” The problem isn’thackers—it’s malware, phishing attempts, and advertisements. If you’ve evernoticed a lot of advertisements about something you recently searched for, thereason is because a website or service is tracking your searches. Perhapsthere’s no malicious intent behind it, but it is a violation of your privacy.

According to statistics, there is a cyberattack every 39 seconds—and 43% of all cyber attacks target small businesses.Even a stray credit card number can be a massive headache to correct. If you’venever dealt with identity theft before, count yourself lucky. It’s not at allfun to resolve.

Take the time to read through this articleand think about how you can improve your cybersecurity. While we recommendFirefox as a browser option, there are steps you can take to improve youronline safety no matter what your preferred browser is. As the world movestowards an increasingly online society, it’s up to individual users to protectthemselves.
