New submission from Nabil Stendardo <nabil.stenda...@bluewin.ch>:
This seems to be a long-standing issue for a long time, given that the "banner"
gets printed before the argument list gets parsed, and so cannot get removed
with a command-line argument. My solution is to use an environment variable
(which I named FF_NO_BANNER, feel free to change it) when it is equal to the
string "true" to remove the banner. Hope that's useful.
