Hi,
As I tried to investigate the temporary file permission I noticed the
/tmp/mozilla_mozillaUser0 directory which led me to :
- https://bbs.archlinux.org/viewtopic.php?id=206506 then to
- https://bugzilla.mozilla.org/show_bug.cgi?id=1233434
This explains everything and the workarounds are pretty easy to implement.
Sorry I could not find this earlier since I focused on Debian BTS. At the
same time, this report is now here for the record...
I hope this shall be fixed in the version presently in experimental since
the Mozilla bug reports indicates this is fixed in upstream 44.0 b4.
Bye,
phep
