Thunderbird refuses to save my password for my e-mail account.
[I have originally asked this question in German, this is the English translation]
Hello!
Unfortunately Thunderbird refuses to save my password preferences.
I now have to enter my password every time I start it. Each time I enter it, I have also checked the box asking Thunderbird to save my password using the integrated password manager. After I have entered it and logged in successfully, I see that Thunderbird does not save it, because no saved password is displayed under “Privacy and security” -> “Passwords”.
I am using the latest version (I checked under “About Thunderbird”). I do not use CCleaner. My OS is Windows 10, my inbox works normally and I can see my emails and send new ones.
How can I fix the problem please?
