I was all over the place with my first post.   

the apparmor profile for firefox is in extras

/usr/share/doc/apparmor-profiles/extras

I'm trying  firejail compiled with apparmor support.   But I need to spend a good few weeks studying firejail .

------------------------------------------------------

I'm too much of a novice to understand, but I've always seen what seem to me, strange DBUS logs.

I also get plenty of logs whenever I enable apparmor on firefox, about denied operations.   Maybe everybody does.

Anyways.   UFW wouldn't install because I messed up my sources during install somehow.
I got it working.   

For me, it's local network devices I'm concerned about.  My P.O.S xfinity modem comes standard with telnet, and like 4 other services.

So my own MODEM I'm leary of.

The xinfinity public wifi is shared , via my router, to the public even though I asked Xfinity to turn it off.
I know this because the MAC ADDRESSES are the same.

Theres that company in Europe I believe, that found like literally 30 ways to hack Xfinity modems.   

Speaking of all over the place, is this a normal passwd file?   I did install virtualbox.   I don't remember the passwd file having that many entries at first.
