107678 - cannot set mime-type in browser prefs

Status: VERIFIED DUPLICATE of bug 109236

(Core Graveyard :: File Handling, defect)

Description

[bobj]

Cannot set up mime-types via the browser prefs.  It seems that you need
to also set up the Windows file type to make these work.

Running:
  Mozilla/5.0 (Windows; U; Win95; en-US; rv:0.9.4) Gecko/20011019 Netscape6/6.2

Selected Edit|Preferences|Navigator|Helper Applications menu
Clicked on New Type...
Created a text file with the contents
  "contents of foo.foo"
and saved the file with the name: "foo.foo"

Opened the local file , "foo.foo" in the browser.

Expected: Downloading foo.foo dialog which would ask if I want the file
opened by the executable or saved to disk.

Actual:  Opened foo.foo as a text file and displayed its contents in
a browser window.

However, after created a new file type in the Windows File Explorer,
this worked.  I opened the File Explorer, and then:
Selected the View|Options... menu
Selected the File Types tab
Clicked on New Type...

Entered the following:
  Description of type:  Foo file
  Associated extension: foo
  Content type(MIME):   application/foo
  Default extension for content type:   .foo (automatically filled in)
  Actions:
       <left blank>

bill sez this should go to networking:file.

this is because content sniffing overrides content-type for local files.

Making this a dup of bug 109236, since that one has a patch.
