Hello I have been using proxychains with firefox for some time, I decided to install firejail to add more security, but when I try to run firefox with proxychains seems that firejail blocks it. The browser is opened but proxychains don’t seem to run properly. I am using Parrot I think is based on Debian.

This is the output when I start proxychains with firefox:

$proxychains firefox
