Password is reset every time I go edit a users settings

So if for example I need to go into
Sites --> site --> Users&Email
Then click on a user to say add an alias, firefox tend to overwrite the password.
Maybe if there was a check box like phpmyadmin has, to say yes change password then it would keep from happening happens.
For example I setup a user.
They change their password.
Then I need to go in and change something it goes back to their old password.
???
Thanks for all your hard work and a great program.

Have you configured Firefox to automatically fill in passwords?

 

Yes ) -:

But would it be possible to circumvent this feature by having a check box and then adding it to the code so if not checked then do not change password?
Like the check box could say, "Check Here to Update" phpMyadmin does the same.
