FreeBSD 12.0 or try -CURRENT. Only kernel matters, you can postpone
upgrading base/userland and ports/packages as long as the kernel config
contains COMPAT_FREEBSD10 and/or COMPAT_FREEBSD11.

Background:

  An innocuous change in Firefox 63 made tabs hang on *every* page, so a
  Mozilla engineer that maintaines IPC code got curious and tracked it
  down to a kernel bug. As Firefox IPC is based on old Chromium IPC I
  made a guess that Chromium may suffer from a similar issue but whether
  it's related to the notorious hanging tabs is unknown.
