I'm now trying to rejoin Thunderbird with the same email name but it won't accept the current Microsoft account password (almost certainly now different from previously).

Recently I had a hard drive failure while doing a backup. Somehow Windows and almost all apps and personal data. was lost. I downloaded a fresh copy of Thunderbird and can't get past either auto or manual configuration because I lost and do not remember password. When I try to add a new account, I always get the THUNDER MAIL screen which is Greek to me . How can I enter a new password? or is possible to use the PRIMARY password? I am going to try and see if i can get a current profile to use . Is there an easier way to achieve this? I still have my 2 earthlink accounts but again no password.

I have been on Windows 11 for years. While trying to fix a password issue, I learned that Firefox thinks I am on Windows 10 whose support is going away. How can I tell Firefox that I am on Windows 11?

Related issue: Firefox no longer likes my password. It has 8 characters, but only letters and numbers. Things got messed up while trying to fix it, so I am not sure of my password anymore. Apparently Firefox and Mozilla have separate accounts. I don't know which system's password is broken.

It was suggested that I clear cookies and cache. I cannot find the menu to do that. Trying to fix each problem just creates more problems! I need some support to straighten things out.

My old desktop used Windows 7 and I used Thunderbird as my mail. I had a tech help and transfer files to a new desktop running Windows 11. Mail came over but he said he couldn't use thunderbird for a reason??? and switched it to Spectrum Mail which I don't like. I would like to restart a thunderbird mail account again but don't remember my password and my old computer has been destroyed. Any way to do this without starting from scratch and losing all my old mail and contacts?
