The Best Firefox Password Managers of 2026

If Firefox is your browser of choice, you’ll need a password manager that’s Firefox compatible. These password managers can help you generate and remember strong passwords, fill out online forms, and secure information in Firefox and beyond. Review our list to find the best password manager for you, your family, or your business.

RoboForm remains one of the fastest and most affordable password managers, and it runs especially well on Firefox. Its browser extension is lightweight and easy to navigate, making it a great pick for anyone who wants secure, no-hassle autofill. In my testing the login capture and form-filling features work nearly instantly, especially on e-commerce sites and multi-page login forms.

The Firefox extension gives users direct access to stored logins, identities, and bookmarks. RoboForm also supports two-factor authentication (2FA), password health reports, and secure folder sharing. Users can choose cloud syncing or opt for local-only storage for tighter control over their data, something you won’t find in every manager.

While the desktop app feels a bit outdated, the Firefox extension delivers one of the smoothest autofill experiences we’ve tested. For a manager that’s both fast and secure, RoboForm continues to offer incredible value.

Who is RoboForm best for?
Firefox users who want fast, accurate autofill and strong security at one of the lowest prices available.

Recent upgrades to RoboForm:
Recent updates improved the Firefox extension layout, enhanced form-filling logic, and added more granular access controls for shared folders.

Proton Pass offers a dedicated Firefox extension that covers the essentials for Firefox users: passkeys, a password generator, hide-my-email aliases, and built-in 2FA codes. According to Proton, the extension works on Firefox-based browsers. In our review, autofill in the browser extension worked well.

The free plan includes unlimited logins, notes, and credit cards across unlimited devices, along with 10 hide-my-email aliases and up to three 2FA items. Pass Plus adds unlimited aliases, unlimited 2FA codes, secure vault sharing, file attachments, and Dark Web Monitoring. Passkeys work in the Firefox extension on every plan.

Proton Pass encrypts all vault fields, not only passwords, using 256-bit AES-GCM. All apps are open source, and the company is based in Switzerland. Proton says Recurity Labs tested the browser extensions, the mobile and desktop apps, and the command line interface from January to April 2026 and found no remote exploits or encryption bypasses. Personal plans are limited to email support, with no live chat or phone option.

Who is Proton Pass best for?

Firefox users who want a privacy-focused, open-source password manager with a capable free plan and a full-featured extension.

Recent upgrades to Proton Pass:

In October 2026, Proton added folders for organizing vault items (paid plans), URL matching rules for autofill, and improved compromised password alerts that run on the device and compare a fingerprint of the password against fingerprints from known breaches. Earlier updates include file attachments (spring 2025), Emergency Access (August 2025), and a command line interface (2025).

Proton Pass pricing:

Pass Plus costs $23.88 for the first year, which is $1.99 a month, for new customers, then $35.88 a year, an average of $2.99 a month. Pass Family covers up to six people for $33.48 for the first year, which is $2.79 a month, for new customers, then $59.88 a year, an average of $4.99 a month. The free plan includes unlimited logins, devices, and up to 10 hide-my-email aliases. There is no trial. Proton offers a 30-day money-back guarantee on paid plans.

Keeper is one of the best password managers available for Firefox users who want strong security without sacrificing ease of use. Its Firefox extension is sleek, fast, and intuitive, offering direct access to your vault, autofill capabilities, and quick password generation. In testing, Keeper performed reliably on Firefox, autofilling login forms and saving new credentials with minimal issue.

One of the standout features of Keeper is its customization. The vault interface allows for multiple views (list and grid), color-coded records, and tagging, making it especially helpful for users who manage lots of credentials. I found it simple to navigate and set up, with autofill accuracy on par with top competitors.

Keeper’s security is also among the best in class. It uses AES-256 encryption, supports biometric logins, and offers add-ons like BreachWatch for dark web monitoring. Although BreachWatch requires a separate subscription, it’s a valuable layer of protection.

Who is Keeper best for?
Keeper is ideal for Firefox users who want flexible vault organization and premium security tools like secure sharing and advanced 2FA options.

Recent upgrades to Keeper:
Keeper now supports passkeys on Firefox, offers improved autofill for complex web forms, and added a self-destruct sharing feature for extra privacy.

Keeper pricing:
The personal plan starts at $1.79/month. The family plan, which includes five premium accounts, starts at $7.08/month or $4.96/month with current promotions*.

RoboForm is our top pick for Firefox password managers. Proton Pass earns the second spot with its privacy-first design, open-source Firefox extension, and built-in features like passkeys, aliases, and 2FA codes. NordPass rounds out our top three with strong encryption and a clean interface. Keeper is also a strong choice for advanced vault customization and secure file storage.

What sets our top three apart is their balance of usability, security, and price. RoboForm offers the fastest autofill and one of the lowest price points. Proton Pass brings open-source transparency, Swiss-based privacy, and a generous free plan with unlimited logins. NordPass pairs XChaCha20 encryption with a clean, beginner-friendly interface.

Each of these password managers runs smoothly on Firefox and offers browser extensions that support one-click logins, password capture, and autofill. Whether you’re managing logins for work, family, or personal use, any of our top three will provide a secure, user-friendly experience.

Other password managers we considered but didn’t rank among the top include:

• Bitwarden: Offers excellent value with strong 2FA support, but limited form-filling and more manual setup.
• Dashlane: Great UX and bonus features like a VPN, but the free plan is limited to one device.
• 1Password: Highly secure with advanced access control, but lacks passkey support and has limited free options.
• LastPass: Easy to use with a well-designed interface, but past data breaches and tiered limitations hold it back.

On the surface, all password managers essentially fulfill the same functions — generating and storing passwords. In creating our list of recommendations for the best password manager, we dug deeper, comparing software on what matters most, including price, platform compatibility, security, and other factors.

I signed up for a plan with each provider to test:

• Plan value: A balance of plan features and affordability
• Platform compatibility: Usability across a range of platforms, devices, and browsers
• UX: Ease of navigation and intuitive structure
• Form filling: Consistency and convenience of auto-filling forms and vault customization
• Security: Encryption method and security breach history
• Two-factor authentication (2FA): Range of 2FA options, such as authenticator apps, security tokens, and biometric factors
