Running Firefox in Firejail

Hello,

I always ran firefox in firejail with Daedalus. 

I installed Excalibur and tried to do the same thing but it gives me the error message. 

I ran firefox like this:
"admin@MySys:~$firejail --seccomp firefox"
but it gave me errors.  So I ran
"admin@MySys:~$firejail firefox"
but it still gave me errors.  What can I dd?  Below is the result.

admin@MySys:~$ firejail --seccomp firefox

Re: Running Firefox in Firejail

I get the same output as you up until this line:

Error fcopy: invalid ownership for file /etc/localtime

What does 'ls -l' have to say about that file? (Mine is a symlink owned by root.)
