You can use Moz Backup next time so you can keep your profile, cookies and log in data intact. Please be sure you use the same version of Firefox/Thunderbird your backing up fromNot to mention that the win10 64 recent updates deleted some of my saved logins to various websites in my Firefox. It doesn't happen all the time- just occasionally . What a PITA.
hmmm- good idea. I will look into that. I have just started writing down my logins these days because of the windows 10 issues.
FF does have it's own pw manager
Firefox also uses sink too, so if you wish you can go mobile with ff on your phone with your passwords saved within ff. I personally do not see a need for a third party app but I do believe the apps you suggest are very good apps. I do not know if ff encrypts your passwords when you use ff sink because I do not use the sink option in ff. I do not believe that my cell phone is secure and do not use it for personal things like log ins and email
I use LastPass on browsers and phone. They also have desktop apps available. But it requires you to enter in your master password (or fingerprint on mobile) before you can access your password vault.
