PassFF Firefox

PassFF

Add-on that allows users of the unix password manager 'pass' to access their password store from Firefox

Features & Capabilities

PassFF is a Firefox add-on that connects the unix password manager pass (passwordstore.org) to your browser. Once the companion native host is installed, PassFF can read your pass store, present matching entries in the browser, and optionally autofill and auto-submit login forms for a seamless sign-in experience.

This extension requires that you already use pass and have it configured on your system. Follow the project homepage instructions to install the native host application. PassFF is designed for existing pass users and is open source — see the project README and host installation guide on Codeberg for full setup and security details.

User Reviews

PassFF is valued for making the 'pass' password manager easier to use within Firefox, featuring a simple setup and reliable performance for many users. However, recurring issues include host app connection failures, limited format support, and occasional installation challenges. Despite some usability quirks, it remains a helpful tool for those seeking better Firefox integration with 'pass.'

  • Simple and quick setup process, works well out of the box for many users.

  • Reliable and effective for everyday usage as reported by several users.
  • Enhances integration of 'pass' with Firefox, appreciated by users preferring to use 'pass' over built-in browser password managers.
Cons
  • Issues with connection to the host app leading to errors like 'Connection to the host app failed or returned an unexpected result!'.
  • Limited compatibility: works only with two formats, and doesn't support some features like copying line numbers in entries.
  • Installation of the host app can be problematic or fail silently for some users, leading to inability to use the add-on.
  • UI quirks such as popup width being too small for some users with long directory paths in password entries.

Is PassFF Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

PassFF requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

PassFF is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
