I know this has been posted about before.
But I have to let off some steam someplace
I just tried to log into my cell phone service account by using my computer.
I could not get it to log on.
I started a conversation with that online, click here for help, can we help you, person
After about 10 minutes of give and take messages.
I asked could my browsers cookie setting be causing this issue.
A short wait for an answer and I get back.
OH! you are using Firefox.
You need to be using Chrome browser to be able to log in!
Used Chome browser and logged in with no problem.
