Observed on Windows 95 and Windows 98 with Build 2001061804 (and other recent
builds over the past week)

Set up a helper application for mime type application/x-zip-compressed

make the default action "Save to Disk" and make sure that "ask me before opening
downloaded files of this type" is NOT checked

Attempt to download any ZIP file, for example,
http://HamsterRepublic.com/dl/wh_demo.zip

The expected behavior would be to immediately pop up the dialog that asks you
where you want to put the file on your hard drive.

The actual behavior is that it pops the "What should Mozilla do with this file"
dialog

This is a fairly recent regression, within the past week or two. It was working
before.

The problem is that your system might use a different mimetype like
"application/x-compressed". Did you recently installed a new zip/unzip utility?

My currently registered unzipping program is FastZip 2001, which I installed on
February 14th. I have not changed it since, and Mozilla WAS working correctly
inbetweentime

I check this out a little more, and here is what appears to be happening:

The server hamsterrepublic.com is sending a mime type of "application/zip" for
.zip files. I have verified this by grabbing the raw headers.

_if_ have a helper application set up for application/zip (I did not yesterday
when I reported this) then mozilla correctly obeys the settings for the helper app.

but when there is no such helper appfor application/zip then Mozilla looks up
the mimetype in the windows registry according to the file extension .zip

What it finds there is the mime type that FastZip 2001 set, which is
"application/x-zip-compressed"

I do (and did) have a helper application set up in Mozilla for
application/x-zip-compressed but mozilla ignores it, and asks me what I want to
do with the file.

Confirmed on Win98 using build 2001061804 win32

In this case Mozilla is actually matching the file extension and not the mime
type. Should mozilla trust the file extention this way? I think mozilla should
display and use the actual mime type used by the webserver and not the mime type
found in the windows registry that matches the file extension.

dup of bug 46655 ?

I don't think that this is a dup of bug 46655.  We are getting the correct mime
type, it is just ignoring the helper application setting in the case of
application/x-zip-compressed, application/x-zip-compressed and application/x-tar
seem to work.  I have not tested with applications of the form
application/x-gzip-compressed, as all gzipped files that I have found have gzip
as content encoding and report their uncompressed mime type.  This makes
selecting a helper file for tar files problematic.

This bug is either a dup of bug 78943 or at least depends on it. Adding depend.

dependancy sounds sounds right. Lets wait and see what happens to these symptoms
after bug 78943 gets fixed.

on linux, moz does not honor it if i uncheck the "Ask before opening..." box in
a mimetypes edit-box. Also reported in bug 98115. Changing OS to all.

Dupe/related to bug 48948?

This looks to be the same bug as 78943.
