Sure. Download the profile and copy it in /etc/firejail/
Notice that the profiles must bear the application (executable) name and must
end in .profile
In this case it is **start-tor-browser.profile**
Then you make yourself a launcher, either in your panel or in your menu
pointing to the executable.
In terminal and in the launcher the liner is (assuming your username is
necrotroll and the folder of your TorBB is .tor):
firejail /home/necrotroll/.tor/Browser/start-tor-browser
I really love "menulibre" for easily editing menu entries and I recommend it
because it is simple and nice.
To check if it works properly I suggest you first try it in terminal. You
should see this output:
necrotroll@localhost:~$ firejail
/home/necrotroll/.tor/Browser/start-tor-browser
Reading profile /etc/firejail/start-tor-browser.profile
Reading profile /etc/firejail/disable-common.inc
Reading profile /etc/firejail/disable-devel.inc
Reading profile /etc/firejail/disable-passwdmgr.inc
Reading profile /etc/firejail/disable-programs.inc
The first line is telling you firejail is using the profile..
If you have other relevant questions don't be shy, just ask.
But stop necroing, it's not very fun, just like any other thing after a
while, even the best joke in the world gets stale very soon :))
