Widocznie na Firefoksie 60 i powyżej ani xpinstall.signatures.required
ani config.js trik opisany powyżej prac (Mozilla, kila nad proszę!).
Wspomniane powyżej rosyjskie forum najwyraźniej wymienia również rozwiązanie dla tych wersji Firefoksa. Zamiast tego umieść to w config.js, który następnie zapisz w C: \ Program Files \ Mozilla Firefox

Następnie musisz dodać to do pliku config-prefs.js zapisanego w C: \ Program Files \ Mozilla Firefox \ defaults \ pref
pref("general.config.obscure_value", 0);
pref("general.config.filename", "config.js");
pref("general.config.sandbox_enabled", false);
Został przetestowany do pracy na FF 66.0.3. Niestety nie przywróci magicznie dodatków i motywów, ale przynajmniej ponownie włącza opcję ich ponownej instalacji. I tak jest lepsze niż cokolwiek, co Mozilla ma do zaoferowania, ponieważ wydaje się, że nie obchodzi ich to szczególnie pomimo faktu, że ich fora są zalewane skargami na ten problem.
