A password manager for Firefox is an add-on that fills in your logins and saves new ones, connected to the password manager account or app behind it. The add-on is the front door, and the vault is what you're choosing. Ten follow in no particular order, with users and ratings from Mozilla Add-ons.
Picking a password manager add-on is really picking a password manager. The Firefox add-on fills in and saves logins, but your passwords live in the service or app it connects to, so that's the decision that matters.
Every detail below comes from each add-on's Mozilla Add-ons listing as of Oct 2026: users, rating, number of ratings, last updated date and publisher. If you're leaning towards open source, my guide to open source password managers goes further.
Password manager add-ons for Firefox compared
I chose these from the listing details alone: users, rating, number of ratings, last updated date and whether Mozilla's recommended badge appears. The free plan column says Yes only where the listing text names free use; Not stated means it didn't. Nothing here comes from my own trials.

The add-on is the front door, the account is the house
Every add-on here connects to something bigger: an account with the company or, for the KeePassXC plugin, the KeePassXC password manager itself. So the questions that matter are about the vault: can you open it on your phone, can you share it with family or staff, and how would you move your passwords out if you ever wanted to?
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
- One person, one vault, no fuss: a manager whose listing names a free plan.
- You already use one on your phone: the add-on from that same company, so everything stays in one vault.
- A team or family sharing logins: a manager whose own site offers a shared or business plan.
- You want passkeys as well as passwords: a manager whose listing names passkeys.
Where the Mozilla ratings split
Here's a detail that's easy to miss. On Mozilla Add-ons, ratings for these add-ons run from 3.5 for Norton Password Manager to 4.8 for Proton Pass, as of Oct 2026.
Big names don't always rate well in the browser. Several well known services sit below 4 on their Firefox listings, so if you're torn between two services you like equally, the add-on's rating and its newest reviews make a fair tiebreaker.

Set it up safely in Firefox
- Install the add-on only from Mozilla Add-ons, and check the publisher matches the company you signed up with.
- Choose a long master password you've never used anywhere else.
- Turn on two factor sign in for the vault itself.
- Once your logins are in the vault, switch off Firefox's own password saving so you aren't keeping two copies.

My plain advice on choosing a password vault
Choose the service first and the add-on second. If you already use one on your phone, install its Firefox add-on and keep everything in one place. If you're starting from scratch, a manager that names a free plan on its listing is an easy way in, and you can move up later if you need sharing.

Frequently asked questions
Does Firefox have its own password manager?
Yes, Firefox can save passwords on its own. A separate password manager add-on gives you a vault you can use in other browsers and on your phone too.
Are password manager add-ons for Firefox free?
Some listings here name free use in their own text, and the rest don't say. The free plan column shows which, as of Oct 2026, and each company's own site has the full plans.
Is it safe to keep passwords in a browser add-on?
The add-on is only the front door; your passwords sit in the vault behind it. Install from Mozilla Add-ons, check the publisher and protect the vault with a strong master password.
Why are some big password managers rated low on Firefox?
Mozilla ratings reflect how people feel about the add-on in Firefox, not the whole service. Read the newest reviews to see what's behind a low number.
Can I move from one password manager to another?
Usually, yes. Most services let you export your vault and import it into another, but check both companies' help pages before you start.
