Who can reply me in german language? 2 years ago I have set a master-password. For some months, after switching on my PC, the system asked for this master-pw and I introduced it. Later, the system did no more ask for this master-pw.....and therefore I forgot it. Maybe I have modified something, but I do not remember, I am now 81 !!! Up to now everything runs well........ but I fear problems should this change!!! For example if I should need to replace the existing PC. I just found a very long recovery key of firefox. What can I do?? I am definitely not an experienced user.
