'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.
In a perfect world, you would never allow a web browser to save your passwords. Why? Because web browsers aren't exactly the most secure pieces of software on your desktop. To complicate matters, most modern browsers allow you to sync your passwords with an account, so they are available to any browser associated with that account.
That's not good. Worse, you could wind up with your accounts being accessed by someone other than yourself.
What do you do?
Well, if you absolutely must have Firefox save your passwords, you need to protect them with a Primary Password. Once you've enabled the Primary Password (formerly called Master Password), you'll be prompted to type that password every time you open Firefox, and any time you want to view a saved password.
Fortunately, this is easy to do. The one thing you have to keep in mind is that if you forget that Primary Password, you're in for a challenging ride. In order to reset that password, you have to open Firefox, point it to chrome://pippki/content/resetpassword.xhtml, and then click Reset. However, when you do that, everything you've saved will be lost.
So, if you want to keep those saved credentials intact, it's in your best interest to not lose that password. To that end, you should consider using a password manager and creating a very strong and unique password as your Firefox Primary Password.
How to protect your Firefox saved passwords with a Primary Password
Are you ready to set up this option? Let's do so.
The only thing you'll need for this is an updated version of Firefox. I do recommend you always keep your web browsers updated to the latest versions to avoid software vulnerabilities. That's all you need. Let's set that Primary Password.
1. Open Settings
Open Firefox and then click the menu button (three horizontal lines) at the top right of the window. From the drop-down menu, click Settings.
2. Navigate to Logins and Passwords
From the Settings window, click Privacy & Security in the left pane, and then locate Logins and Passwords.
Click the check box for Use a Primary Password. A pop-up window will appear, where you enter and verify the Primary Password. You'll also see a very clear warning about remembering the Primary Password. Take heed of this warning and take note of your Primary Password (preferably in a password manager).
4. Click OK to set your Primary Password
Click OK and your Primary Password is set. Now, any time you start Firefox or attempt to view a password in Settings > Privacy & Security, you'll be prompted for that password.
Congratulations, you've added a much-needed layer of security to Firefox. Now, the only person who can view your saved passwords is you. Even with this added protection, you should consider not allowing your web browser to save your passwords and, instead, use a password manager.
