This plugin will allow you to access your zx2c4 pass repository directly from Firefox.
It will try to auto fill and auto submit the login form if a matching password entry is found.
- You need zx2c4 pass installed on your computer
- You will also need a working password repository
- Download the last release of the plugin here.
- You can then manually install the plugin in Firefox from the addons page (Firefox/Add-ons/Install Add-on from File...)
Alternatively, to use the git version:

A black icon with a P should appear in your Firefox toolbar. From here, you will be able to browse your password repository or search using a case sensitive Fuzzy matching algorithm. The shortcut to open the menu is: Ctrl-y So considering this repository
<Ctrl-y>M1<Enter> will send and authenticate you on MySite1 (<Shift-Enter> to open in a new tab)
Current supported features are:
- Fill and submit
- Goto, fill and submit
- Copy login to clipboard
- Copy password to clipboard
Additionally, if you added the url property in your password info, you will be able to go there by clicking directly on the password menu. (left-click same tab, middle-click new tab)
An accepted format for the password info is:
<the_password> login: <the_login> url: <the_url> <other_inputfield_name> : <inputfield_value>
Additional password, username, and url tags may be defined through the preferences dialog.
PassFF will also try to find login password and url inside the direct child of a pass node. For example, if you have a structure like this:
- get the login from the "login" entry for supersite.com
- get the login form the "login" field inside the mysite.com entry for mysite.com (see format above)
Fields names can be set in the preferences.
From the plugin preferences you will be able to set:
- Inputs (A comma separated list of input names. Input field names in a html page containing one of those values will be filled with the corresponding value.)
- Passwords input names.
- Login input names.
- Fields (A comma separated list of field names. The first matching field in the password data or in the store tree will be used as the corresponding value.)
- Login field names.
- Password field names.
- Url field names.
- Pass Scrit params
- The pass script path.
- Pass home. If empty, use User home.
- Location of the gpg agent info file containing environment variables (relative to the home).

To enable debug mode, just go in the addon preferences and check the "Enable logs" check box at the bottom of the dialog box. You then have to open the Browser console (Tools/Web Developper/Browser console) You should see many lines about passff. You could Filter on "[PassFF]" if you want
If you're experiencing problems running passff or have some encoding issue, try using the "through shell" approach in the preferences (under "Pass Script").
NOTE: This method may also be applicable if GPG fails to provide a pin entry dialog, or if you experience otherwise unexplained issues with incorrect login and/or password data.
Configure the script's execution parameters appropriately:
- Set "User home" to the absolute path to your home directory
- Set "Pass command" to the path to the
passbinary (if installed with homebrew, the default location is
- Set "Pass shell" to your preferred shell (e.g.
- Set "Shell arguments" to
With those settings in place, the plugin should be able to find your passwords.
If you're still having trouble, it may be due to a bug present in version 1.6.5 and earlier of pass. From your shell, check the output of
pass list. If the passwords listed end with
.gpg, then your version of pass contains the bug. The bug was fixed in this commit. You must update your version of
pass or manually apply this patch to the pass script on your machine. Once
pass list lists passwords with the
.gpg stripped off, the plugin should work!
