Why use a password manager for Firefox ESR on macOS

Managing dozens of logins by hand is both insecure and time-consuming. On macOS with Firefox ESR (Extended Support Release), a dedicated password manager provides:

  • End-to-end encryption of your credentials, isolated from browser exploits.
  • Cross-device synchronization (desktop, mobile, tablets) without relying on browser sync.
  • Automated form-filling, strong randomized password generation, and breach monitoring.
  • Compatibility with Firefox ESR’s extended support cycle and Apple’s security model.
