Indeed.

-Legion scanning crashes when in 'Hard Mode'.

-I've tested on Dual Boot and Kali 'live' USB stick.

-Scanning DOES work (in 'Hard Mode') when Legion is 'run' via command line as "sudo legion" BUT, when Firefox is directed to open a found port, it is refused. The error in the terminal reads "Running Firefox as root in a regular user's session is not supported. ($XAUTHORITY is /run/user/1000/gdm/Xauthority which is owned by atdtphreaker.)
root@kali:/usr/share/legion#" (see 'attached' screenshot for error)

Thank you. Your time is greatly appreciated.

Upstream instruction is to use 'sudo'.
I can change the script /usr/bin/legion to force the use of sudo.

But the Firefox issue will remain and it's more complicated. I will try to find a workaround.

Thank you_

+Okay, I assumed it may be a bit complicated.

I appreciate your time and focus on this issue.
