The Best Password Managers for Firefox 2024

The Mozilla Firefox built-in password manager is convenient but not the most secure password vault. Built-in password vaults are more vulnerable to cyberattacks than third-party password managers that use military-grade encryption. 

In evaluating the best password managers compatible with Mozilla Firefox, we looked for features like strong encryption, password-sharing functions, two-factor authentication (2FA) or multi-factor authentication (MFA), autofill and password generation features, and more. Keeper is our top pick based on its advanced security features. We'd also recommend 1Password and Dashlane. Here's why.

• Keeper: Best for security
• 1Password: Best for features
• Dashlane: Best for affordability

Keeper: Best for security

Who it’s best for

Keeper is best for individuals, families, and enterprises seeking a password manager that puts security at the forefront. Keeper’s suite of security-focused features includes:

• Zero-knowledge security architecture
• Robust encryption
• Vault offline access
• Secure password sharing
• Secure cloud backups
• Unlimited devices and syncing
• 24/7 customer support
• Emergency access

What we liked

We really value Keeper as a comprehensive, top-notch password management solution that emphasizes zero-trust security. It is authorized by FedRAMP and StateRAMP, which indicates that governments trust it. It utilizes AES 256-bit and PBKDF2 military-grade encryption to protect your data at all times, and it provides end-user security audits of password strength and password reuse. Moreover, because Keeper is based on a zero-knowledge architecture, it permits only the user to access their encrypted data, meaning Keeper itself cannot even access it.

Keeper offers various authentication options: 2FA, MFA, and passwordless authentication. It also has unique features like secure file storage, secure password sharing, offline access to your password vault, and BreachWatch, which monitors your personal information on the dark web to check if it has been compromised.

We also appreciated its cross-functional compatibility with various platforms and devices, like its Keeper Firefox extension. Per its website, Keeper works on every smartphone, tablet, and computer. Its comprehensiveness makes it suitable for personal, family, and business use. Plus, Keeper offers 24/7 customer support — called Keeper Concierge — available to users anytime they need support or training.

Finally, it is routinely audited and meets compliance standards with:

• Sarbanes-Oxley (SOX)
• SOC 2
• ISO 27001
• GDPR
• PCI DSS Level 1
• HIPAA

What we didn’t like

Unlike other password managers, Keeper Password Manager does not offer a free plan. Another drawback that may not sit well with some users is that additional features, like secure file storage, Keeper Concierge, and BreachWatch, are all add-ons not included with any Keeper plan. You'd have to pay extra for secure file storage, Keeper Concierge (24/7 customer support), and BreachWatch (dark web monitoring).

1Password: Best for features

Who it’s best for

1Password is perfect for those seeking a convenient autofill feature, so you don’t have to waste time inputting or memorizing passwords. Additionally, anyone who prioritizes security would appreciate its Watchtower feature, which monitors compromised websites, weak and reused passwords, 2FA, and more.

What we liked

We liked that 1Password’s autofill feature is intuitive and that the password manager is compatible with various operating systems and browsers. The 1Password Firefox add-on is also easy to download from the Mozilla Store, so you can begin using it immediately after creating an account with your master password.

1Password also has customizable settings for generating strong, unique passwords for different scenarios, including logins, bank accounts, wireless routers, and more. This makes it ideal for anyone seeking a one-stop password management service. Other sensitive information, like medical records, passport documents, and Social Security numbers, can also be securely stored in 1Password and shared with authorized persons if necessary.

Additionally, we liked that 1Password is committed to security and values your privacy. It offers end-to-end AES-GCM-256 encryption and PBKDF2 key strengthening. 1Password also undergoes periodic security assessments by multiple third-party security firms, and it maintains a transparent privacy policy.

Aside from protecting your information with Transport Layer Security (TLS), 1Password also uses Secure Remote Password (SRP). SRP creates a different encryption key for each session, which prevents replay attacks.[1] SRP provides an extra layer of protection to protect your information from being read, even if an attacker decrypts TLS.

1Password also offers:

• 2FA: Allows an authenticator app, YubiKey, or biometric access
• Intelligent autofill: Fills out names, addresses, phone numbers, credit card information, and banking details easily
• Phishing protection: Fills out passwords only on trusted sites where they were saved
• Breach Report: Checks the site haveibeenpwned.com to see if any of your accounts have been compromised
• Travel mode: Lets you remove vaults from your computers and mobile devices, except those marked as safe for travel
  
• Watchtower: Alerts you of compromised passwords and helps quickly secure your accounts.

Additionally, 1Password’s standout password-sharing feature has customizable password-sharing settings. You can choose who can access the secure link, set timed expiration options, and decide whether the password can be viewed only once.

Finally, 1Password's Emergency Kit helps you securely and systematically create a digital will or legacy, enabling trusted people or chosen heirs to access your vital digital assets. The Emergency Kit is a PDF document containing your account details and a place to write your 1Password account password, which is intended to be printed out, stored in a safe space, and shared with the people you trust.

What we didn’t like

Despite 1Password's robust security and unique features, there are still some drawbacks. First, the lack of a free version might deter users who are seeking a cost-free option. Additionally, 1Password doesn’t issue refunds should you decide that 1Password isn’t a fit for you. Lastly, the setup process for creating a digital will or digital legacy may be somewhat cumbersome since you must manually print the Emergency Kit.

Dashlane: Best for affordability

Who it’s best for

Dashlane is a user-friendly password manager that still offers many features. Dashlane's features, like its strong password generator, secure password and note sharing, and intuitive autofill engine, make it a valuable tool for anyone who manages multiple online accounts and wants to streamline their digital lives.

Dashlane is also great for anyone on a budget because it offers a free plan, and its starting price is only Free.

What we liked

We appreciate that Dashlane has a free plan without requiring a credit card. It also has essential password manager features like secure sharing, strong password generation, unlimited password storage, and autofill.

Although Dashlane wasn’t available as an add-on in the Mozilla Firefox store, we liked how it provided easy download instructions from the Dashlane browser extension webpage. We also liked that its user-friendly interface makes managing passwords a breeze.

 

Key features we enjoyed include:

• Support for an unlimited number of devices
• Password health check with actionable insights
• A Sharing Center that lets you sync devices and share secure passwords and notes
• 2FA for added security
• Dark web monitoring and personalized security alerts
• Emergency access for trusted persons in the event of an emergency
  

Dashlane plans include access to HotSpot Shield VPN, a virtual private network that enables Wi-Fi protection and secure browsing. This standout feature sets it apart from other password managers, offering users an extra layer of privacy and protection when browsing online.

Furthermore, Dashlane has partnered with HackerOne and its Bug Bounty Program, which allows security researchers to find any security vulnerabilities in the product. This is a step in the right direction toward enhancing its security.

What we didn’t like

Dashlane does have its shortcomings despite its solid feature set and security measures. For starters, its privacy policy dances around some critical details. It mentions sharing hashed personal data for ad targeting and with "affiliates," but leaves users guessing what exactly that means. This is a drawback because users should receive crystal-clear explanations about how their sensitive data is protected.

Another area of concern is Dashlane's approach to security audits. They rely on internal audits rather than third-party assessments, which could raise concerns about how reliable their audits are. Being more transparent with their privacy policy and allowing third-party security audits would undoubtedly strengthen user confidence.

Also, Dashlane’s free password manager is limited in its offerings. It supports only one device and doesn’t offer dark web monitoring or a VPN for Wi-Fi protection like its Premium, Family, and Business plans do.
