161485 - Mozilla should not add extension based on mime type when extension already presnet

Status: RESOLVED DUPLICATE of bug 164816

(Core Graveyard :: File Handling, defect)

Description

[Xavier Poinsard]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020623
Debian/1.0.0-0.woody.1
BuildID:    20020623

Mozilla is adding a file extension corresponding to the mime type of a file
regardless the file has already one.
For example, the web server is sending a file named alert.csv with mime type
application/vnd.ms-excel. But mozilla is adding .xls to the file name which
cause Excel to misinterpret it.
I would expect that Mozilla, like IE, keep the file name unchanged but propose
to open it according to the mime type.

Reproducible: Always on windows 2000 and linux
Steps to Reproduce:
1. make a web server generate a file with a mime type whose extension is
different from the file name extension
2. try to save it with mozilla
3.

Actual Results:  It will add the extension of the mime type

Expected Results:  It leave the file name unchanged but used the mime type to
open it
