Sometimes I use firejail…well a lot actually….and I usually just use it for a browser like this:
firejail –private google-chrome
or this
firejail –private google-chrome –proxy-server=”socks5://localhost:8080″
But on a few occasions I want to be able to join ssh to the same sandbox instance…so I do this:
firejail –list
firejail –join=3452
(or whatever the session you want)
Another thing I have ran into is I downloaded something but want to save it before I destroy my firejail (private) session…so I do this:
firejail –get=5255 ~/.config/google-chrome/Default/Cookies
