428908 - Wrong management of file downloaded name

Status: VERIFIED DUPLICATE of bug 301328

(Toolkit :: Downloads API, defect)

Description

[G. Negrelli]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13

When I download a file from web for more than one time, since Firefox find it on cache, the original name of file is renamed in this way:
DownFile.doc -> DownFile-1.doc
IE renames the file in this way:
DownFile.doc -> DownFile[1].doc

But if my file has a double extension the renaming rules are different between the two browser.
Firefox:
DownFile.doc.p7m -> DownFile.doc-1.p7m
IE:
DownFile.doc.p7m -> DownFile[1].doc.p7m

.p7m is a real extension for digitally signed file (very common file in Europe).
The PKCS#7 signing standard doesn't expect that the real file name is stored in some field.
When a program try to validate the sign on this kind of file has no problem, but if a program try to open the contained file (p7m is a sort of envelop) Windows can't do that because Firefox has damaged the original extension (DownFile.doc-1) while IE manteins it (DownFile[1].doc)

Reproducible: Always

Steps to Reproduce:
1. Download a file with double extensions
2. Download it again

Actual Results:  
First download
DownFile.doc.p7m -> DownFile.doc.p7m

Second download
DownFile.doc.p7m -> DownFile.doc-1.p7m

Expected Results:  
First download
DownFile.doc.p7m -> DownFile.doc.p7m

Second download
DownFile.doc.p7m -> DownFile-1.doc.p7m
