I am suddenly being made to login to 'Firefox Sync' and it is asking me for a password. I have no idea whatever what that password might be. I've guessed a lot but no luck. I am permitted to reset the password for 'Firefox Sync' but if I do then Firefox Sync is threatening to destroy all my recorded passwords (is that what it is saying? I daren't ever try it in case they are all lost). I have no idea what most of these passwords are (they are random secure ones generated as once-off streams of characters) and if I do reset my password, I will lose everything. What can I do please? Why is it suddenly asking me for a password, please? I am very, very worried that I have lost everything. Have I missed something? I must never use any of this security stuff again, I think: it's too dangerous. I will just have to to keep a copy of all my passwords in a file on my computer from now on away from Firefox so this doesn't happen again. I've had to create a new account (using my existing account would involve resetting the password, which, again, threatens to kill all my passwords) to ask this question.
