If the idea is to prevent previous tabs from opening on startup, that only
works for me if firefox is already running when I run
firefox --safe-mode
...which may not be possible for Sophie.
Removing the line:
user_pref("browser.startup.page", 3);
from
/home/username/.mozilla/firefox/XXX.default-esr/prefs.js
has the desired effect (where "XXX" is the appropriate string of letters and
numbers).
There may be more than one such profile directory, in which case, if other
users don't rely on tabs being restored, then remove that line from all the
XXX.whatever/prefs.js
files you can find.
It may also be necessary to add the line
user_pref("browser.sessionstore.resume_from_crash", false);
I don't know if the order of lines matters. In my prefs.js, this appears in
the sequence
user_pref("browser.search.region", "GB");
user_pref("browser.search.widget.inNavBar", true);
user_pref("browser.sessionstore.resume_from_crash", false);
when added from about:config, but the 2nd line is non-default as well as the
3rd, and these are only present if added manually or set in settings or
about:config, as appropriate.
Hope that helps
Gareth
