I went through MLB......I can access via Safari bit not Firefox. They say it is your problem. I want this fixed or I will switch my browser preference to something else.
Does Websites look wrong or appear differently than they should help? can you give an example link and explain what's not working?
This is what I get:
Authentication Error. Please check email and/or password and try again..
Only on Firefox, not Safari.
So, it's your username/password being wrong. Are you using a saved password? Password Manager - Remember, delete, change and import saved passwords in Firefox
I deleted the old password as you suggested, but am still getting the same message when I try to sign in on Firefox.
Please enter the required information below to continue.
Authentication Error. Please check email and/or password and try again.
I already have an MLB.com account E-Mail Address: Enter Your Password:
