1170298 - ftp download/listing not working (electrolysis)

Status: RESOLVED DUPLICATE of bug 1144631

(Firefox :: Untriaged, defect)

Description

[wing-tung Leung]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:40.0) Gecko/20100101 Firefox/40.0
Build ID: 20150529004007

Steps to reproduce:

Open new tab and enter FTP URL (company internal vsftpd daemon):
ftp://defrlpas021.mle.mazdaeur.com/dsr/PRDdsr/LogWAS8/PRDdsr01c/dsr-checklist.log

(using latest Firefox Developer Edition 40.0a2 on MS Windows 7)


Actual results:

Page stays blank instead of showing content of log file.

For FTP directory listing, the page also simply remains blank.

ftp://defrlpas021.mle.mazdaeur.com/


Expected results:

Show login popup (FTP is login/password protected) and show actual file content downloaded via FTP.

For directory listing: also request credentials, followed by actual directory content if login succeeded.

This seems to work fine with multi-process disabled, but "breaks" in multi-process mode. Strangely enough, it looks mainly like a problem on our internal, secured FTP server, and NOT on a public FTP server file (e.g. ftp://ftp.belnet.be). Not all secured FTP hosts result into this problem, other protected FTP hosts seem to work fine.

Some info about our FTP server:
ftp> system
215 UNIX Type: L8
ftp> rstatus
211-FTP server status:
     Connected to ************
     Logged in as **********
     TYPE: ASCII
     No session bandwidth limit
     Session timeout in seconds is 300
     Control connection is plain text
     Data connections will be plain text
     At session startup, client count was 1
     vsFTPd 2.0.1 - secure, fast, stable
211 End of status

Is there additional logging/tracing I should enable to provide more info?

Hmmm, probably duplicate of bug 1144631. Sorry for finding out AFTER reporting this.
