Hi,
The below description pretty much explains it in full technical
details and matched my problem symptoms:
>>
Description hrvoje.habjanic 2015-12-17 13:49:39 PST
User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:43.0)
Gecko/20100101 Firefox/43.0
Build ID: 20151210085006
Steps to reproduce:
On a single host (ubuntu 14.04.3) i have multiple users. Each of them
uses remote desktop (x2go) to connect and browse. When first user starts
browsing (firefox), and tries to download something, a special file
/tmp/mozilla_mozillaUser0 is created.
When second (different) user try to download something (not the same
thing!), clicking on download link does not produce “Save to” dialog, or
saves file to designated location. Instead, new entry is added to
download manager, with status “failed”.
Actual results:
On first user download, “save to” dialog is presented, and user is able
to save file.
On second user download, there is no “save to” dialog and file is not
saved. Instead, file is logged in download manager with “failed” status.
Both users have selected to show “save to” dialog!
Expected results:
Second user should be able to save the file.

Hi.
It would seem that /tmp/mozilla_mozillaUser0 directory is to blame in
here. It is created when first download is attempted, and it is not
deleted or moved away. Also, it have 0700 permissions, so other users
can not access it.
Removing this directory, enables other users to download normally, BUT,
again, because is recreated, next user again have the same problem.
Changing permissions to 0755 makes this work next user - because new
directory is created - “mozilla_mozillaUser1”. But, again, with 0700
permissions, which make jet another next user having the same problem.
What is interesting in this whole mess, is that assigning TMP
environment variable makes this directory not showing up, and thus,
fixing this bug.
Regards,
H.
