Required: I'm trying to run headless selenium (using PHPUnit) on fresh CentOS 7 minimal.
Problem: It seems I installed everything correctly but firefox is not launching and my selenium web driver stuck at
14:45:31.646 INFO - Launching Firefox.... With firefox command, I'm getting following output
[admin@EE ~]$ /usr/bin/Xvfb :1 -screen 0 1024x768x24 &  11932 [admin@EE ~]$ export DISPLAY=:1 [admin@EE ~]$ firefox firefox:11936): Gtk-WARNING **: Locale not supported by C library.

Can someone please suggest why selenium is not able to identify Firefox?
