Autofill doesn't appear when doing account creation and subsequent login

When I create an account on any website, Firefox proposes a strong password and I use the prompt to automatically fill in the "create passwords" fields. However, Firefox doesn't seem to save that password to be used for subsequent logins. I am not seeing any "save passwords" prompts after creating an account. Perhaps related: During account creation sometimes a website ask for your home address. Firefox doesn't seem to have an autofill prompt for my address. I was wondering if the issue was due to my decide (iPhone 14, 26.6.2) so I tried the account creation process on chrome and it worked without problems. Maybe my Firefox settings are hindering somehow ? I have the strict privacy protections switched on. Reading on the potential limitations it wasn't clear to me that address autofill and password saving was going to be affected.
