246184 - Extension ".exe." not recognized as ".exe"

Status: VERIFIED DUPLICATE of bug 246280

(Toolkit :: Downloads API, defect)

Description

[Jan Moesen]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040607 Firefox/0.8.0+ (MOOX-AV)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040607 Firefox/0.8.0+ (MOOX-AV)

When trying to download a file with an on-server extension of ".exe.", the
download manager does not recognize it as being the same as ".exe". On Windows
you can't have a filename end with a ".", it just gets stripped. That means that
".exe." yields ".exe", which is an application. The DM does not recognize it as
such, and enables the "Open with" option.

Reproducible: Always
Steps to Reproduce:
1. Download a file ending in ".exe." (http://jan.moesen.nu/tempz0r/nc.exe.)
2. Choose "Open With" without specifying anything
Actual Results:  
It ran the executable.

Expected Results:  
Give the usual executable warning.

In .htaccess, I added these lines:

<Files nc.exe.>
        ForceType application/octet-stream
</Files>
AddIcon /icons/binary.gif .exe.

The Content-Type is the same for "nc.exe." as for "nc.exe":
"application/octet-stream". The executable is netcat, but that doesn't matter here.

I realize this is not something likely to occur in the wild. FWIW, IE's
behaviour is even stranger: it saves the file without an extension ("nc[1]").

Sorry, should have been Firefox instead of Browser.

Confirming, and stealing description from bug 246267.

Based on comments in bug 246280, it sounds like this bug was fixed there.
