Firefox: Remember new passwords without prompting

Question

How can I make Firefox automatically remember all passwords without prompting?

Answer 1

Hacking Firefox to Always Auto Save Password Without Showing Notification Bar:

1. Close Firefox
2. Edit nsLoginManagerPrompter.js with notepad which is normally located in C:\Program Files\Mozilla Firefox\components\

3. Replace the entire lines 642 to 711 with the code below:

   var pwmgr = this._pwmgr;
   pwmgr.addLogin(aLogin);
   

Now whenever you login to any website, Firefox will auto save the site, username and password to the login manager WITHOUT showing the notification bar.

Note: even when you enter the wrong username or password, it will still be saved.

Looks like this site here has the answer you are lookin' for here

It states that you must have all instances of Firefox closed, navigate to the "C:\Program Files\Mozilla Firefox\components\" directory, open up nsLoginManager.js and comment out lines 112 and 121

Answer 3

for firefox 4 -extract omni.jar located on the firefox folder and then open the components folder -edit what you need -then compress it, using zip format or it will not work, and name it omni.jar -note: dont compress the folder "omni" compress whats inside the folder -replace your omni.jar with the one in the firefox folder

Answer 4

On a mac FF3.6, the edits are made in:

• In the finder, go to the Applications folder
• Firefox (right click and select "show package contents")
• Navigate to Contents > MacOS > components
• The file has the same name: nsLoginManagerPrompter.js
• MAKE A BACKUP COPY OF THIS FILE! But you knew that :-)
• Edit lines 815 through the end of the function - 850.

Here's my change complete - which make the end line 854.

        var pwmgr = this._pwmgr;

    // phil
    pwmgr.addLogin(aLogin);

    /* phil
    var buttons = [
        // "Remember" button
        {
            label:     rememberButtonText,
            accessKey: rememberButtonAccessKey,
            popup:     null,
            callback: function(aNotificationBar, aButton) {
                pwmgr.addLogin(aLogin);
            }
        },

        // "Never for this site" button
        {
            label:     neverButtonText,
            accessKey: neverButtonAccessKey,
            popup:     null,
            callback: function(aNotificationBar, aButton) {
                pwmgr.setLoginSavingEnabled(aLogin.hostname, false);
            }
        },

        // "Not now" button
        {
            label:     notNowButtonText,
            accessKey: notNowButtonAccessKey,
            popup:     null,
            callback:  function() { /* NOP * / } 
        }
    ];

    this._showLoginNotification(aNotifyBox, "password-save",
         notificationText, buttons);
     */
},

I kept everything but commented out what I didn't want, and added the pwmgr.addLogin(aLogin) line.

Answer 5

This DOES still work in Firefox 3.6 - 4.0+, it's just not in the same place as shown in the picture.

Using Firefox 4.0:

Edit nsLoginManagerPrompter.js which is normally located in C:\Program Files\Mozilla Firefox\components\.

Replace the code from lines 800 - 869 with:

var pwmgr = this._pwmgr; pwmgr.addLogin(aLogin);

Save and replace original file.

Et voila!

Saves passwords and doesn't prompt.
