When I try to open my online account it says "bad request"

Hi Priscilla, sorry to hear that. Could you add what is the website you're facing issues with?

the website is citi

Online Pay: Go to the Citi Homepage and enter your User ID and Password. Select Your Card: Navigate to your accounts overview and click on your credit card. Click Make a Payment: Choose the "Make a Payment" option from your account details. Enter Details: Select your payment amount (Minimum Payment, Statement Balance, Current Balance, or a custom amount). Add Source: Pick your linked checking or savings account (or link a new external bank account using your routing and account numbers). Schedule & Confirm: Select the payment date, review the details, and click "Submit".

Mobile App Pay:

Open the Citi Mobile App on your smartphone. Tap Your Card: Select the specific credit card you wish to pay. Tap Make a Payment: Press the primary payment button on the screen. Confirm details: Input your payment amount, select your funding bank account, choose a date, and submit.

You could also just call Citi customer service at 1-800-950-5114 to pay through the automated system.

Hope that helps!

Is that citi.com ? Do you still get the bad request message? Do you see it when you try to log in with other browsers as well?

The error message is in the other thread: support.mozilla.org/questions/1593806
