Linux operating systems
It is recommended to not operate Security Enhanced Linux® (SELinux) in enforcing mode while ITDT-GE is running.
Replace with the appropriate path to your installed Firefox version before ITDT-GE is started.
a) ln -s /usr/bin/firefox /usr/local/bin/mozilla or b) export MOZILLA_FIVE_HOME=/usr/lib/firefox<version>
If you are using the Gnome desktop, be sure to log in to the desktop session as root to use ITDT-GE to prevent device access issues.
ITDT-GE requires GTK3+ to run since version 9.4.0. On Linux systems with GTK2, ITDT can be installed or updated but does not start afterward.
