I have created cronjob as @reboot root sleep 75 && firefox but then I test it, but it didn't work. In /var/spool/mail/root it shows me this

enter image description here

what I want to archive is after every reboot I want to automatically load my firefox browser. Want to do it with this with cron job or even with systemd unit file as Crontab job start +1 min after @reboot

    I recommend you copy and paste the `text` from the screen instead of a picture of the screen. The primary reason is that it's considered good etiquette on unix.se, and will help you get answers more quickly. – RobertL Sep 24 '18 at 02:58

    You should probably put the desired commands in the startup for your desktop system, KDE, Gnome, etc. Or maybe X window startup. You can't really run firefox until X is running. – RobertL Sep 24 '18 at 03:09

A cronjob is not the correct way to do so.

For Firefox to be able to run, your X environment (KDE or GNOME) must have already started. Hence the error about $DISPLAY mentioned in the last line of your input.

Therefore you need to configure KDE or GNOME to run Firefox upon start. For instance, here's a related question regarding GNOME: https://askubuntu.com/questions/37957/how-do-i-manage-applications-on-startup-in-gnome-3
