I tried to change my password but could not find an acct key, don't even remember having one! This is a new computer and it worked fine until I say that you are showing a very old picture for my account and showing I'm still on Windows 10!!! That is VERY OLD and I've used Firefox for years!!! I changed from Windows 10 to 11 on 7-1-25. Someone has hacked my account I guess!

What to do???
