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

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

Thanks jbr! Since there is another question about this, I will close this one as duplicate and continue the conversation there.
