Updating Ask Fedora User profile

How fast does a user profile need to be updated before it could be a bug or something security related ?

I just logged into the forum on my macbook through a Mozillla Firefox browser (which I not able to update to the latest). I realise that the profiles picture is different refering to eachother at same time logged into my Asus W75 on exactly the same time, How does time an updating works. Should I concern and sharing this neither just igonore it.!
