Firefox by default doesn't ask for login unless you have sync setup to which it might have asked to login setup when you start Windows and clicked yes to which now it starts when windows starts.

If those don't work then it's becomes a Windows support request help at that point.

Are you using Sync as this is a possible reason to ask for the Primary Password when you start Firefox ?

Using Sync is a possible reason to ask for the Primary Password at startup. This is because the credentials to login to the Sync account are stored in the Password Manager and you need to enter the Primary Password to unlock the passwords and connect/login to the Sync account.

Neither of these solutions fixed my problem. This only happens when I shut my computer down and re start it. It is OK if I just put the computer to sleep and wake it up.
