Firefox for iOS Community Forum

I was orrdering services from GROOME TRANSPORTATION online a few minutes ago, and got a message to SAVE my bank debit card info to FIREFOX which I thought was part of the booking process of this vendor. It was not. I want to remove any and all of my debit card information from Firefox immediately! Please respond ASAP.

HOw do I stay signed in to Firefox so I do not have to sign in everytime I open it? Also, I created a new password which is being rejected. Since I can see the password, I know its the right one.
