Can not remember the password

hi, my TB version 91.4.0 on Linux Deepin. TB was downloaded as .tar.baz2 and put it in /usr/lib/thunderbird.

When i receive mails, TB let me type the password and then i chose “remember it in password manager”.

But this dialogbox will popup again later. Then i went to check the password in performance(password manager), there was no record.

And i try to set primary password, it said " can not set ".

When i went into TB troubleshoot mode, the password can be remembered, but after quit the mode, it gone. :joy:

I don’t know why and need help, thanks a lot

:joy: :cold_face:
