For Firefox 3.5 on Linux, you can find the nsLoginManagerPrompter.js file in /usr/lib/xulrunner-1.x.x.x/components/ folder where x.x.x is the version of xulrunner you are using.

Works like a charm on Yahoo Mail. Thank you for the easy to follow instructions and snapshots. As Ryan indicated, after I updated to Firefox 3.5.4, I had to re-do this simple change to the js file (I opened it with Notepad and searched for the “_isAutocompleteDisabled” section as instructed) and I’m on the road again.

Is there a way to just get rid of the prompt completely but having firefox automatically remember all passwords?

I tried it with ff3.5. It still does not work with hotmail. Has anyone been able to do it with hotmail.

Many thanks.

First, let me tank you for this trick, it worked, FireFox once again ask if I’d Like it to remember my Password. While making the change in the
C:\Program Files\Mozilla Firefox\components\nsLoginManager.js folder, I ran across what seemed to be some strange looking script, but maybe it is how FireFox wrote it, I don’t know but it looked like someone was trying to obtain my passwords. Here is a snip out of the script I found this section just above were you make the true false change, if needed I can post the full file, but this is the part that jumped out at me. Does anyone else have this same script, or is someone trying to hack me? Thanks for any help.

username field found)”);

// If we’re not submitting a form (it’s a page load), there are no
// password field values for us to use for identifying fields. So,
// just assume the first password field is the one to be filled in.
if (!isSubmission || pwFields.length == 1)
return [usernameField, pwFields[0].element, null];

// Try to figure out WTF is in the form based on the password values.
var oldPasswordField, newPasswordField;
var pw1 = pwFields[0].element.value;
var pw2 = pwFields[1].element.value;
var pw3 = (pwFields[2] ? pwFields[2].element.value : null);

if (pwFields.length == 3) {
// Look for two identical passwords, that’s the new password

if (pw1 == pw2 && pw2 == pw3) {
// All 3 passwords the same? Weird! Treat as if 1 pw field.
newPasswordField = pwFields[0].element;
oldPasswordField = null;

I need help…Gmail suddenly quit saving my login info, so I followed the suggestion online to remove my saved Google password (in Firefox) — but after I erased it, I incorrectly assumed I’d be offered the option to “save this password” anew, which I have not been. I’d like to try your method here, but when I click on the “nsLoginMgr” I get an error code “WIndows Script…Syntax error…Microsoft jscript compilation error.” (and that ominous sound like I’m doing something wrong!) Is there an easy way to get around this? Or should I try reinstalling Firefox? I am a beginner w/all this code stuff, but your explanations above seem easy enough for me to try.
Thanks in advance if anyone can help!

Thank you, Ryan! I looked all over the web for a solution to this problem! Excellent tip! Worked well. Fixed my problem. It was easy as pie to find, to understand and to do the simple modification. You did a great job explaining it. An 8 year old could do it. It rocks. People like you are the reason I choose to stay with an open-source browser.

OK, that is my anonymous post above.
I am still having problems with login.yahoo.com
Only, now it works about 9/10 times.
Which makes it very difficult to debug.
