OK, I hope this is not the one million and first question about this problem :) I didn't find any similar question.
I have a Stack Exchange account, and when I try to sign in to it, Firefox doesn't suggest saving my account and password. It seems is because of that log in the page's properties.
Is there any solution?
Edit: It works correctly with other sites, and I am logged in while have not deleted the cookies, but when I delete the cookies and try to log in, there is no suggestion because Firefox has not saved anything.
Briefly when I enter my username and password, I want my browser to ask me "Remember this account?" like other sites do.
