When I go to this site:

http://www.filelibrary.com/Contents/Multi-Platform/100/41.html

and I try to download this file:

rechtt.zip

Mozilla saves the file as a .exe file instead of a .zip file.  As a result, the
file can't be opened with WinZIP.

Reproducible: Always

Steps to Reproduce:
1.Go to http://www.filelibrary.com/Contents/Multi-Platform/100/41.html
2.Try to download the file: rechtt.zip 
3.It will be saved as a .exe instead of a .zip

Actual Results:  
File was saved as a .exe instead of a .zip

Expected Results:  
File should be saved as a .zip.

Reporter:
Have you assigned application/octet stream to an application in
edit\preferences\Navigator\helper apps ?

Comment 2

[tom.williams]

I have NOT changed the "application/octet stream" setting and it has defaulted to:

Description: Application
Extension: .exe
When Encountered: Save file to disk

So, I also noticed an "application/x-zip-compressed" setting which IS set to WinZIP.

Why would the MIME type NOT be "application/x-zip-compressed" since I'm
downloading a .zip file?

Peace......

default= no entry for application/octet-stream and please remove that entry.

Because the server sends application/octet-stream for this .zip file.
Ask the server admin why he does that.

Is it possible for a PHP download script to determine what MIME type
a file is _before_ Apache sends the HTTP headers?

That did the trick...  I don't know how that default entry got created since
I've never touched those settings.

Thanks!

Peace....

I don't know PHP but i know that the server sends "application/octet-stream" as
header for this .zip.

open http://webtools.mozilla.org/web-sniffer/ , enter a .zip URL from that page
and see the content-type

Yes.
