I jumped at the chance to install Firefox 64 bit at the end of December after using 32 bit version for a number of years. Only now I've realised my passwords and logins are all missing. I've looked at the restore profile suggestions but it seems like 64bit has by default overwritten the 32bit profile, including the passwords, unless it's gone to another place that I cannot locate? Any suggestions for a win10 user to retrieve my lost password?

Thank you
