When creating or changing the Personal Security Password, you get the security 
alert saying that you are submitting a form to an insecure site.  But you are 
not submitting it to any site -- you are merely clicking on OK to a 
browser-generated form.  It's inappropriate (and misleading) to get the alert at 
this time.

Here's the stack-trace (no surprises) at the time the dialog appears:

No, this is not a dup of bug 39518.  That bug has to do with the checkbox to 
disable the dialog in the future.  This bug has to do with the box coming up in 
the first place.  We should never get this dialog when telling the browser that 
you want to change your master password.  This has nothing to do with 
transmitting data to a site -- it's totally a privilegded communication between 
the user and the browser.

Oops, yes - definitely two separate issues!

Steve, can you walk me though: "creating or changing the Personal Security 
Password"?  I tried:

Tasks->Privacy and Security->Password Manager->Change Master Password...

This resulted in psm.exe crashing.  Am I doing the wrong thing?

Comment 6

19 years ago
You are doing the right thing.  That's exactly what I do to get the dialog.  Are 
you sure you have a good installation of psm?

Comment 7

19 years ago
Are you sure it crashed or did it simply assert?  Yes, there are many assertions 
when psm comes up and thayes is probably going to clean that up eventually.

Comment 8

19 years ago
Yes, it crashed dereferencing 0x00000.  The psm install seems to work fine for 
https pages.  I'll try a clobber build and reinstall.  At any rate, this is 
probably a bug in the psm glue code not form submission.  The psm glue code is 
what determines if a dialog should be popped up or not.  CC'ing dougt

Comment 9

Do you have the latest and greatest version of psm?  I know that they made some 
changes recently which are needed for proper operation of SDR but might not be 
needed for https.  So that could possibly explain why you can do https but crash 
on this dialog.

I'm pulling a fresh tree right now and will try it out.  But the dialog came up 
fine (no crash) on a tree from two days ago.

Comment 10

With my fresh tree, and with a fresh psm, I am still seeing the problem.  In 
fact, under certain conditions (not sure yet what they  are) I can actually get 
the security alert twice.

Here's a scenerio in which I get the alert twice:

1. Create a new profile and bring up the browser
2. Go to
3. Fill in any arbitrary username and password, then submit form
4. Answer "yes" to the "do you want to save" dialog
5. Dismiss the encryption-disclaimer dialog
6. Dismiss the security-alert dialog (this one is bona-fide)
7. From the menu select tasks->privacy->password-manager->encrypt
8. PSM dialog for creating master password appears.  Enter password and press OK
9. Security alert appears (this is inappropriate).  Click OK
10. Security alert appears again (this is doubley inappropriate).

Worksforme with the 8/29 PSM build for Linux.

Comment 17

Doesn't works-for-me with the 8/29 mozilla build for windows.  Here are simple 
steps to reproduce the problem.

1. Start with a fresh profile
2. From menu do tasks->privacy->password-manager->change-password
3. PSM pops up a dialog with the title "Personal Security Password"
4. Enter a password and confirm it on the dialog
5. Press OK

At this point you get the security-alert dialog saying "Any information you 
submit is insecure and could be observed by a third party ..."  This is the last 
thing you want to see when you are creating a secret password for yourself.  
Furthermore, it is misleading since it implies that you are submitting this 
password to some website which of course is not the case.

JUST A MINUTE!!!  I think we really are submitting this password to a website.  
I just did some debugging on it and it appears as though the password dialog 
itself is coming from the following site:


I'll investigate further by using a sniffer and seeing if that is what is 

Comment 19

What you're seeing is the url between mozilla and PSM, which uses HTTP (with 
basic auth) to display UI.

I have a fix that will supress the security dialog when using security advisor. 
I expect to check this in tonight or tomorrow.

Comment 20

Yep, the dialog for creating a master password is indeed coming from a website, 
so when the user creates or changes his master password it is getting submitted 
back to the website.  That's certainly a privacy breach and probably a security 
breach as well.

I'll attach the network traffic that got generated when I attempted to change my 
master password.

Comment 22

David, I hope the fix you are about to check in does more than just surpress the 
security advisor.  We have much bigger problems if you are going to access a 
website every time a user creates or changes his master password.

Comment 23

Previous traffic that I posted was generated when the user brought up the 
change/create password dialog.  I'm not about to post the traffic that gets 
created when he submits the new password.  It contains some encrypted data which 
I would guess is the users password.

PSM does UI by running a mini-http server that servers up HTML content to a 
client. Here is an internal link that describes the design: 


Comment 26

18 years ago
Is the mini http server actually running on the client's local machine and there 
really is no traffic going out to the net?

Comment 27

18 years ago
Yes. You will see that all the urls use for the host.

Comment 28

OK, I'm satisfied -- there is no privacy or security breach here.  Sorry for 
thinking otherwise.
