Firefox users often care about privacy and open source. A good manager has a reliable Firefox add-on, sync with other devices, and strong encryption. We tested Bitwarden, 1Password, Proton Pass, NordPass, and others in Firefox to compare autofill and compatibility.
Bitwarden and 1Password work very well in Firefox. Bitwarden is open source and free; 1Password has a polished experience. Proton Pass is a good privacy-focused option. Choose Bitwarden for open source and value, 1Password for the best UX, or Proton Pass for privacy and hide-my-email.
The best password managers for Firefox work via official extensions with reliable autofill and sync. We tested 1Password, Bitwarden, Dashlane, NordPass, Proton Pass, LastPass and RoboForm in Firefox with no notable differences from Chrome.
