Why Choose the RoboForm Firefox Extension?

RoboForm offers tons of convenience features such as an automatic form filler and a password strength monitor. It also let us easily share our credentials as needed, which came in handy when sharing our Hulu account with our family.

Firefox Extension

After installing the RoboForm Firefox extension, it prompted us to save our account details anytime we logged into a new account. Most password managers can do that though. RoboForm makes things easier by allowing us to name the credentials and choose a folder to store them in. That kept our accounts organized in our RoboForm vault.

While signing up for a new account, RoboForm also automatically fills out the sign up form for you. We signed up for a cloud storage account while testing RoboForm which required our email and all of our billing information. To make that process quicker, we went into the RoboForm extension under the tab titled as our name and clicked “Fill Forms.” That automatically populated the sign up form with all of the information RoboForm has. It also created and saved our new login credentials.

Pricing

We found RoboForm’s free plan offers a lot for individuals. That said, the account sharing capabilities and credential strength monitoring is well worth the price of the premium plan. They also offer a family plan that supports up to five accounts. Here’s an overview of RoboForm’s pricing:

Security

RoboForm subjected themselves to a third-party security audit in 2023 and published the executive summary of the results. The auditors found a couple of weaknesses, notified RoboForm of those weaknesses, and then RoboForm secured them. A re-audit confirmed all of the weaknesses were secured aside from one low-risk vulnerability that isn’t exploitable.

When we pair that with RoboForm’s 25 years in the business and industry-standard encryption (256-bit AES) and zero-knowledge architecture, it made us feel comfortable trusting RoboForm with all of our credentials.

Why Choose the Keeper Firefox Extension?

Keeper is one of the best password managers in 2025, and its Firefox extension offers excellent value. We found it very simple to navigate and use, and its autofilling feature works very well. Plus, Keeper also uses high-end security features to protect your logins.

Firefox Extension

We used Keeper’s Firefox extension over the course of a week, and we had an overall great experience with it. We like how intuitive the design is. We also think Keeper makes it very easy to add new logins in the extension — especially since it provides access to a built-in password generator. We timed it, and it took us less than 20 seconds to add a new login to our password vault.

The extension also has many useful settings. For example, there’s a “Password Suggestions” setting. If you turn it on, Keeper will automatically generate and suggest a strong password to use when you click on the password field on a sign-up page. We tested this when signing up on different websites (like Facebook, Reddit, and X), and it always worked very well. We also like how Keeper’s Firefox extension has a setting that alerts you if you’re trying to autofill your login on websites that don’t use HTTPS (meaning they’re not secure).

Pricing

For this guide, we’ll only focus on Keeper’s consumer-oriented subscriptions. For personal use, there are two subscription tiers: “Personal” and “Family.” They both come with the same password manager features. The “Family” tier just adds five private password vaults, shared folders and logins, 10 GB of secure file storage, and permission management.

Keeper is a bit pricier than other top password managers, but we think it’s worth it since it offers excellent value. You can also try it out risk-free since it has a free 30-day trial, and you don’t need to share any payment details to qualify for it. Once the free trial ends, you can use Keeper for free. But keep in mind the free version is limited — it’s only available for one mobile device, and it only lets you secure ten logins.

Security

We found that Keeper protects your data using industry-standard security features. It secures your logins using 256-bit AES encryption, which is the same level of encryption used by banks or the military. Keeper also operates on a zero-knowledge model, which means it doesn’t have access to your logins. The company has also undergone an independent security audit, though we wish Keeper would also name the agency that performed the audit.

Why Choose the 1Password Firefox Extension?

If you like to read reports to ensure your digital security, 1Password has you covered. They publish the results of their third-party security audits. We read through them, and we’ll go over them later since it’s not the only reason to choose 1Password. The other aspect we like a lot about 1Password is the admin control in their Families plan. It lets you limit logins to any account from any device in the plan. That works as a great parental control. They also offer one of the best password health monitoring features we’ve seen.

Firefox Extension

The Firefox extension for 1Password worked well when we tested it. We were annoyed, however, that we had to put in our credit card to get it up and running, unlike NordPass and Dashlane. After we put our credit card in, the extension ran as we expected it to.

It worked in the background allowing us to input passwords with the click of a button. Sure, we had to log back in to 1Password every so often, but the overall experience was good.

Pricing

There’s no getting around 1Password’s lack of a lifetime free plan. When we download a browser extension, the last thing we want to do is pull out our credit cards. But, 1Password made us. That said, they offered a month-to-month plan, so we didn’t have to pay for at least a year upfront like with NordPass and Dashlane’s premium plans. They also offer a 14-day free trial to test out 1Password’s full suite of features.

Here’s an overview of 1Password’s pricing:

Security

The main selling point for 1Password’s security is their publicly published third-party security audits. In the last penetration test, 1Password’s most significant vulnerability was on their Windows app. So if you’re using the browser extension, you’ll be safe. In fact, none of the five vulnerabilities found in the last penetration text applied to their Firefox extension. As such, using it on Firefox is one of the most secure ways to use 1Password.

Now, five vulnerabilities might sound bad. And we won’t try to tell you it’s a perfect score. But if it was only given a pass or fail grade, we’d consider these results a passed test. Why are we telling you this? Well, most companies that subject themselves to third-party cybersecurity audits do not publish the reports and instead only tell you if they passed the test. The transparency that 1Password offers makes us feel more confident that they’ll address every vulnerability found.

Why Choose the NordPass Firefox Extension?

After our cybersecurity experts analyzed NordPass, we concluded they offer better data protection than any other password manager. That means you can know it’s safe when you input a password or secure note into their platform. Even if NordPass suffered a data breach, your information would remain secure. We’ll go into the details of how they do that later when we deep dive into their security. The important part, though, is that if you use Firefox for the privacy they give you, you’ll appreciate NordPass for the same reasons.

Firefox Extension

When testing out the Firefox extension for NordPass, we liked the initial onboarding process. After installing the extension and adding it to Firefox, we were immediately directed to the NordPass site, so we could create an account. We were never prompted to input our credit card, and there was never an attempt to upsell us. Two major pluses in our book and why it made our list of the best free password managers.

Instead of trying to upsell us, NordPass helped us set up our first password. We set up our Gmail account first to test out how it worked as an extension. So we added our account and password to NordPass and then signed out of Google. When we signed back in, all we had to do was click our account and then hit the log in pop-up from the NordPass extension. It filled our password for us, which means we no longer need to remember our Gmail password and can use a stronger password.

Pricing

The default plan when you install the NordPass extension on Firefox is the lifetime free plan. That gives you access to the full password management suite of capabilities. We could import as many passwords as we wanted and autofill those passwords when logging into our accounts. Even though NordPass didn’t present us with the option to upgrade while signing up, we could at any time through the banner at the bottom of our account.

Here are the options we had for upgrading our NordPass account compared to the free plan:

Security

NordPass has two big advantages over the competition when it comes to security. First, there’s their encryption protocol. They use XChaCha20 instead of AES-256, which is what most other password managers use. XChaCha20 encrypts data bit by bit instead of in blocks. That means someone trying to break through the encryption needs to break through every bit of data instead of breaking through once to get into the entire block.

Secondly, they use a zero-knowledge security architecture. A zero-knowledge security architecture means the provider doesn’t know the information that you store on their databases. They do this by never decrypting your data on their end, so they can only see your encrypted data. This keeps your data protected even in the event of a data breach. And best of all, these practices were audited by a third-party firm to ensure they can’t read your data.

5. Dashlane - Best Firefox Extension

Why Choose the Dashlane Firefox Extension?

Dashlane is a unique password manager. They’re a web-first password manager, which means they don’t have a desktop application for Windows or Linux. Instead, you need to download the Dashlane extension on each of the browsers you use. That means they put a big priority on the quality of their Firefox extension, unlike most providers which prioritize their desktop apps. As a result, Dashlane is one of the easiest to use if you only use one browser.

Firefox Extension

Installing Dashlane on Firefox was just as easy as NordPass. Although, we liked the options they gave us for securing our account. Instead of a main master password, we could also opt for a six-digit PIN that allows us to sign in on known devices. We could set a different PIN for each device we used too. That gave us a bit of extra security when using the PIN instead of a secure master password.

Instead of manually adding our passwords like we did with NordPass, Dashlane works in the background to find which passwords we should add. As we browse the internet on Firefox, Dashlane automatically adds our passwords to its platform. That means we never needed to go through all of our accounts and import them like we did with NordPass. This is why we think Dashlane is easier to use than NordPass on Firefox, although we still prefer NordPass’ security.

Pricing

For the free plan you start off with after adding the Firefox extension, we liked NordPass’ free tier better. With Dashlane, we could only store up to 25 passwords. That might seem like a lot, but once you add up all of your streaming accounts, social media accounts, marketplace accounts and online banking accounts, those 25 passwords get eaten up quickly. We still appreciated the option of a lifetime free plan though.

That said, Dashlane’s premium plans cost a pretty penny. But for a good reason — they come with a VPN called HotSpot Shield.

Here’s an overview of Dashlane’s pricing with a comparison of features to its free plan:

Security

As for security, Dashlane is not quite as good as NordPass, but they still offer enough security for our cybersecurity experts to trust them with our passwords. That’s because they use AES-256 encryption to protect our data, the same encryption protocol the U.S. government uses to keep classified data secure.2 If it’s good enough for classified data, it’s good enough for our passwords.

That said, Dashlane hasn’t subjected itself to a third-party security audit yet like Keeper, NordPass and 1Password have. We see that as another drawback, but they still use a zero-knowledge security architecture, so we should still get those same protections.
