Setting extensions.torlauncher.start_tor to false removes Tor config panel
The start-tor-browser
script (Linux) explains how to use Tor Browser with a system installed Tor. One of the options to set is extension.torlauncher.start_tor (to false). However, this option effectively and entirely removes the Tor panel from about:preferences
.
Since documentation mentions this panel (and contains screenshots of it), it may be better to disable options that I can't use when using a system installed Tor, instead of entirely removing the panel. Not finding this panel at all may give a feeling that someone has tampered with the installed Tor Browser (as it did for me).
