My FreeBSD 11.2 server does not have X or Firefox -- it has the console, an SSH server, jails, and one service per jail. Each jail has its primary server plus the SSH server. I use a laptop and an SSH client to do administration on the jail host and within each jail. The laptop has Firefox with Disconnect, HTTPS Everywhere, NoScript, and Privacy Badger extensions. Firefox is set to remember nothing. The extensions are set restrictive. I try to do one browsing task at a time. I temporarily loosen the various settings as required as I visit each site. When a task is done, I close Firefox and open a fresh copy for the next task; this wipes the old data and resets most settings. When Firefox locks up, I try to close it. If that fails, I use a terminal to kill it. If that fails, I reboot the laptop. The server has been up for 25 days. David
