User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; de-AT; rv:1.7.2) Gecko/20040906

when following a link from a https site to a http site that immediately
redirects to a https site the warning will be skipped.

Two pages to demonstrate: Locate one reachable as https://localhost/index.html,
the other as http://localhost/redirect.php (note https/http!)

https://localhost/index.html:
<html><body>
This page is reached via https. Come back here via 
<a href="http://localhost/redirect.php">http</a>
</body></html>

http://localhost/redirect.php:
<?
   header( "Status: 302" );
   header( "Location: https://localhost/index.html" );
?>

The link usually stating that an encrypted page is left is not displayed.

When searching for duplicates I have not found this reported, but some
statements, that the warning is merely a user information, especially when no
sensitive data is transmitted (a warning will be issued when https-form content
is submitted to http). However, as links may contain session ids encoded in urls
they may transfer sensitive information unencrypted. 

This mainly protects misconfigured web applications from their own stupidity,
but when the user chooses to be warned the warning should be issued.

This has been reproduced with Mozilla 1.7.2 on Linux (german suse supplied
version) and vanilla 1.7.5 on Windows.

Reproducible: Always

Steps to Reproduce:
1. Make above files available on http and https server
2. navigate to https://localhost/index.html
3. click link to http://localhost/redirect.php
4. You'll be immediately redirected back to https://localhost/index.html without
a warning that you are leaving an encrypted page

Actual Results:  
warning not issued

Expected Results:  
warning should have been issued

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.

If this is still true, it's kinda bad.  A redirect through http could go anywhere during a MITM attack, including an attacker-controlled https site.  I think most users don't have this warning enabled, but users who chose to enable it should be protected by it.

No activity in more than a year.

I don't have a local http/https server installed.

Is anyone still seeing this bug? If not, please resolve WORKSFORME.
