Crashes on all platforms. See the details below here.

Lisa, I think this bug is a showstopper bug.

Mac G3 laptop; OS: 9.1 (branch build: 2001-06-27-03-0.9.2)

1. Launch the browser. (It crashes in both modern and classic themes).
2. However, it crashes more in classic theme than modern theme. 
   (assuming it's in the classic theme).
3. Type this url:
4. Notice that the "Transportation" on your left, click on the "rental cars".
5. Click on "TravelNow" on your right.
6. Click on "San Jose".
7. You would see "what kind of cars"? Under that section, click on 
   "all available" under "Classes" section. And then click on 
    "Search available cars".
8. It lists all kind of car, just click on the first one that saying
   "Book it".
Note: In classic theme, it crashes immediately and sometimes it hangs there.
In modern theme, it sometimes does not crash immediately, therefore, click
on "back" button, and then click on "Search available cars" again, and 
then it crashes.

pmac - do you mean that the browser crashes only when you go to that URL and
perform the action in your steps right?

It doesn't crash just launching with particular theme, I assume, or we'd be in
big trouble :-)

Lisa, Yes, the browser crashes only when go to that URL and perform

*** Bug 88613 has been marked as a duplicate of this bug. ***
The crash is only reproductible when I build with PSM/SSL support
(need to set the environment variable BUILD_PSM2=1).
Does not look like a layout bug for me yet.

I can repro easily with branch build from 07-23. You need to have the SSL

I *think* this is an interaction with this web page doing some not-so-common
focus munging, but that needs to be verified.

I get this crash logging into my bank account on too. (I think you
can get it with a bogus account number as well). If I go to first (forcing SSL on the login page) then I can get into
the account fine - the problem only happens when I get the Secure Website dialog
after pressing the sign-in button.
I created a new profile, and all of the security warning dialogs (Edit |
Preferences | Privacy and Security | SSL) are enabled by default. 

I was able to reproduce this crash on both 98 and NT for I also
reproduced the crash on using Win98. (I had crashed enough
at this point, so I didn't try on NT!)
I was able to successfully log into Schwab and Vanguard using 2001-07-24-06
commercial branch, and I did pass through security dialogs as I logged in and out.
I can reproduce the crash at travelnow, although I have not crashed on that 
site a couple of times. Otherwise, I could fail to login to attinasi's bank 
account :-) without crashing, and succeed at my own account (BofA) without 

I don't know if it's relevant, but the warning on travelnow is not just 
for SSL, but that they are using low-grade encryption.
If I turn off *only* the "Low Grade Encryption" warning in prefs (Edit |
Preferences | Privacy and Security | SSL - "Entering a site that uses low-grade
encryption"), I am unable to reproduce the crash.
I did a trunk commercial debug build last night (12-1am ish) and I don't seem to
be able to reproduce this now. Can anyone confirm that?
I just confirmed with the nightlys, this does *not* crash on the trunk.
saari: Have you built with BUILD_PSM2=1?

If not, the effect is that nothing happen.
No new page is loaded, just like clicking on air.
(just a reminder)
Can anyone else confirm with 2001-07-25 commercial branch that turning off the
"Low Grade Encryption" warning dialog prevents the crash? Thank you.
Turning off the "Low Grade Encryption" warning dialog ahead of time prevents the 
crash. Tested on WinNT - 7/25 branch build.
Yes, turning off the warning prevents the crash. It fixes it for the crash on and (they are different dialogs, but I think it is just the
fact that the dialog is coming up that is the problem - maybe).

On the site, I entered the account number 140000000 and password
9999, press the GO button and I see the warning dialog about going to a secure
site, then it crashes. note: that is my fake account number ;)
If the security dialogs aren't enabled, I don't get the crash.  However, I was
able to reproduce the crash using yesterday's branch build on Win98 with *only*
the "Entering a site that uses low grade encryption" checked.  Here's the
invocation to SSL:

<form action="" method="GET"
name="frm_search" target="_top">

As you can see, the JSP (Java Server Page) is given a long name-value pair since
the method is "GET" and it resides on a secure server.  The "Book It" buttons
each submit the form with distinct name-value pairs.  This, IMHO, doesn't
necessarily constitute "funny page construction" although I'm not a big fan of
the tool generated markup (SoftQuad Software?  Look at the doctype in  If someone can explain what's unusual with the page
construction, this would clue me in!  Otherwise, it appears that the XUL based
security dialog(s) don't jive with the form post to a secure back end.
sorry, i meant form "get" not form "post." :-/
yes, I have both branch and trunk builds with PSM turned on, and it is only
crashing on the branch. 

My first guess would be to look for changes in that dialog's XUL on the trunk
but not on the branch, but I haven't investigated further yet.
I can crash using pmac's original steps to reproduce, using the 7/25 _branch_
builds, and the 7/22, 7/23, 7/24 _trunk_ builds (commercial, win2k). 

However, I cannot crash using the 7/25 _trunk_ build.

That dialog is commonDialog.xul|js, but the only change in the past month
on the trunk is Jul 09, to convert <box> into <hbox>, <box orient="vertical> 
into <vbox>, but that's relatively innocuous, and the changes were correct
(i.e., no changes in orientation direction).
Just in case anyone is thinking of turning "off" the "Entering a site that uses
low grade encryption" warning... I don't think that's a viable solution to this
problem.  Philosophically, it is better to crash in rare cases where this
happens than to give users a false sense of security.

If we can't fix the root cause, then let's ship with the crash rather than
disable the warnings.
Uh, I don't agree Mitch. Crashing is not acceptable, and the warning is of "low"
encryption, which is new to 6.1. All previous versions kept quiet. If you really
don't want a false sense of security, list the algorithm and the key length and
educate users, but of course we're getting off into the weeds real fast. Don't
crash, no matter what.

jrgm, cool, I'll see if I can hunt down why it doesn't crash in the 25th's build
but does in the 24th's. However, I doubt it is going in 6.1 no matter what the
fix is, especially with just switching off the pref as an alternative.
> Don't crash, no matter what.

If this is the case, we have a lot of crashers that happen in equally rare
circumstances that we can pursue without disabling a security feature.  Let's
spend our time on those.  We cannot disable security features.

The Press will attack you for turning off a security feature, but will never
notice that you crash on a rare web site.  Take the crash and fix it in the fall
release with a real fix, dont' disable a feature in the current product.
Adding relnote keyword. This release note wording (added to relnote bug 90577) 
should cover bug 92291 and bug 88120.

Under rare circumstances, Netscape 6.1 may crash if certain security warnings 
are turned on.

These preferences are found under Edit, Preferences, Privacy and Security, SSL. 
Turning off the "Entering a site that supports encryption" and "Entering a site 
that uses low-grade encryption" warnings ahead of time is a workaround to 
preventing a crash.
Keywords: regression, relnote
I completely agree with Mitch. It's a rare crash. Let's not ship without the
security warning. Release note it and find the real fix for the fall release.
