[Reuben Morais]

When rebooting or logging off, Firefox and thinks it crashed, and shows the post-crash session restore page.

Is the environment variable $SESSION_MANAGER set?

[Oliver-henshaw (oliver-henshaw)]

This is probably due to gnome-session (mis-)behaviour:

My test client gets a "Die" message from the xsm server and within a few tens of milliseconds receives an ICE io error (as the server has quit or broken the connection). According to https://www.x.org/releases/X11R7.7/doc/libSM/SMlib.html#Sending_a_Die_Message the server should wait for clients to close the connection.

Status changed to 'Confirmed' because the bug affects multiple users.

[dino99 (9d9)]

This is an unsupported release now. Please think to install the next LTS 'Bionic 18.04'

[Simon Quigley (tsimonq2)]

Marking as Invalid because the release is EOL is not correct. Marking as Incomplete. Also, 18.04 is (at the time of writing) still in development, and you should expect some breakage.

Reporter, is this still present on 17.10 or 16.04?

[Ondrej Mihalyi (ondrej-mihalyi)]

I confirm I see this behavior on a fresh installation of Ubuntu 16.04 LTS. The variable $SESSION_MANAGER isn't set. If I log out or shut down the system with Firefox running, Firefox always shows a message about a previous crash and a button to restore the session.
