Diễn đàn hỗ trợ Firefox

Sometime ago I must have made a typo when entering my email address into a pop-up window in Firefox. Firefox continues to find and use this wrong address in pre-fills but I can't find anyway to correct it. I've worked through Settings/Privacy & Security with no luck. Can someone help please? (Windows 10 Firefox 145.02)

My credit card payment methods are missing from Firefox's settings. I tried enabling every relevant setting in about:config and still they won't appear. My current relevant settings are shown in the attached screenshot. any suggestions?

ive searched every article from here and beyond, but i cannot seem to find the button to edit my payment information. strange since it still prompts to autofill it
