How to Increase Privacy and Security on Firefox – Technipages

Do you like to feel safe when you’re online? Who doesn’t, right? You might already use anti-virus to keep the online threats away, but you can still do some more. By making a few changes here and there, you can make Firefox even more secure. Keep reading to what those changes are.

There are quite a few changes you can make for more security on Firefox. But, it’s up to you which ones you feel more comfortable with. For example, you have the option of adjusting the browser’s Enhanced Tracking Protection. Let’s see how you stay safe online.

How to Stay Safe When Using Firefox

Firefox has the option that allows you to protect yourself against tracking. This option is called, as I mentioned before, Enhanced Tracking Protection. To make the necessary changes, you need to go into the browser’s settings. You can do this by opening Firefox and clicking on the three-lined menu at the top right. Click on Options.

In Options, from the options to the left, click on Privacy and Security.

There are three different options you can choose from. For example, there the standard option. This option blocks:

  • Social media trackers
  • Cross-site tracking cookies
  • Tracking content in Private Windows
  • Cryptominers
  • Fingerprinters

The Strict option blocks:

  • Social media trackers
  • Coss-site tracking cookies
  • Tracking content in all windows
  • Cryptominers
  • Fingerprinters

You’ll also see a warning that some sites might not function properly if you block trackers and isolate cookies. Not to worry, you have control over what can and can’t be blocked.

In the Custom option, you can check the items you want to include. For example, you can choose from:

  • Cookies Cross-site and social media trackers
  • Tracking content – Only in Private Windows or All windows
  • Cryptominers
  • Fingerprinters

If you want privacy without sacrificing usability, it’s best to go with the strict option. But, for maximum privacy, you can always go with Customize. In this option, you can block all cookies or only specific cookies with the Cookies drop-down menu.

You can choose to apply only in Private Windows or in All Windows in the Tracking Content option.

Do Not Track

There’s also an option to send websites a Do No Track Signal. You can choose from two options: Always and Only when Firefox is set to block known trackers. This option is not always useful since companies such as Twitter, Facebook, and Google will not only ignore this petition but even use it to identify you better.

Cookies and Site Data

In the Cookies and Site Data, you can do things such as manually erase the cookies. You can also ask the browser to erase the cookies every time you close the browser.

Also, by clicking on Manage Data, you can see what cookies you have on the browsers and last used.

Logins and Passwords

If your logins and passwords fall into the wrong hands, it can cause a huge mess. Sure, you could save your passwords on your browser, but what if you want to use another browser? You’ll have no choice but to use the browser you have your passwords on.

But, with a password manager, you can use any browser and still have access to all your logins and passwords. Plus, password managers will also let you know how strong or weak your password is. If you have no idea how to create a strong password, most password managers have an option to create one for you.

If you’ve decided to use a password manager, make sure that you erase all logins and passwords from Firefox. You can check by going to:

  • Three-lined menu option
  • Options
  • Privacy and Security
  • Logins and Passwords

You can have Firefox ask you if you want to save your login information for that site. If there’s a site or sites you don’t want to be asked about, make sure to add them to the exceptions list. To see if you have saved login information, click on the Saved Logins option.

If you saved anything, it’d appear right there. To erase the login information, click on the trash icon. You’ll get a confirmation message, just to make sure that you didn’t choose the option by accident. If you don’t have anything saved, you’ll see the following image.

If you only want to erase specific logins, there a search tool on the left you can use.

Site Permissions

When you visit a site, there’s always the possibility that the site will ask you for specific permissions. For example, they might ask you for permission to send you notifications or to access your mic, location, or camera. If you think you may have given a site permission to some of these things, here’s what you need to do to change that.

When you’re at the Permission section, you’ll see a list of permissions. Click on the Settings for each permission to see what sites have access to it or not. To the right, you should see a drop-down menu to either allow or deny the site access. If you never want to be asked for permission for any of these options, click on the block request option when you open them. With this option on, no sites will ever ask you for this permission again.

You’ll need to open and check this option for the permission you want to never be asked about.

Firefox Data Collection and Use

There’s certain information that Firefox sends to Mozilla. You can see what this information is under the Firefox Data Collection and Use section. For example, If left checked, you’re allowing Firefox to send technical and interaction data to Mozilla. You’re also allowing Firefox to make customized extension recommendations, install and run studies, and allow Firefox to send backlogged crash reports on your behalf.

Choose What Info to Synchronize on Firefox

Besides controlling what information is sent to Mozilla, you can also decide what information you want to be synchronized. Click on your profile picture and then on Sync Settings.

In Sync settings you can choose not to share info such as:

  • Bookmarks
  • History
  • Open tabs
  • Logins and passwords
  • Add-ons
  • Options

To modify any one these, click on the Change button.


Firefox has various security option you can modify to keep your data safe. It’s up to you yo take a look at them and decide what you don’t mind sharing and what you want to keep to yourself.
