I am looking for a way to stop my Thunderbird application auto start.

However I don't want to just remove the application, because may I need it in the future, and some important letters are only stored in there.

I tried to check the 'Startup Applications', but I didn't see the Thunderbird client.

How can I stop Thunderbird from starting automatically each time?

--Edit: --

Inside the


Folder I didn't find a thunderbird.desktop entry either. enter image description here

Based on the commenteries, I also tried to check the ~/.config/upstart/ folder, and the .profile file. Unfortunately I didn't find the solution.

Every answer will be appreciated!

    Check if there is a .desktop entry for thunderbird in '/home/user/.config/autostart' and delete it, where 'user' is your username. – Harris Nov 19 '16 at 22:55
  • I've just checked, but there is no thunderbird.desktop inside the .config/autostart/ folder. – Bálint Pap Nov 19 '16 at 23:03

    what files are in this folder, one of them should be responsible for the autostart of thunderbird – db429 Nov 19 '16 at 23:11
  • I've just edited the post above. Seriously I have no idea, I just check each of them. – Bálint Pap Nov 19 '16 at 23:11

In Ubuntu there are basicly three places in which you can set programs to start on login:

  • a *.desktop file in ~/.config/autostart/ in which you define the command you want to run, these files can be set active or inactive via Startup Applications
  • any commands put inside .profile
  • as third place there is ~/.config/upstart/ which is an leftover of upstart, the init-replacement, now dropped for systemd

If nowhere there you can find an entry for thunderbird, things might have got quite funny.

  • Thank you for your comment. I've just checked all the file locations what you wrote. There is no command related to the Thunderbird in the .profile file, and the ~/.config/upstart/ folder is empty. I didn't make any modification for the Thunderbird, I believe it is installed by default. – Bálint Pap Nov 20 '16 at 8:41
