Diễn đàn hỗ trợ Firefox

I am trying to log on to my bank website but it requires something other than Foxfire to log on. I can't figure out how to logon. Can you help? Says my browser needs updated and is no longer supported. I have windows 10 I think.

I have asked the question multiple times, received multiple responses that do not allow access or clear instructions on: how to control Firefox restarts. I cannot get to Settings that has what the instructions say to look for.

Updates have triggered on-boarding loops, Firefox has opened w/o it's title bar, menu bar only appeared intermittently, tabs and address bar were hidden, manual profile relaunches were required more than once, required customization panel to restore tittle bar, my data was almost lost. After much help from AI in fixing some of these problems, new updates caused them to reoccur again and again. I'm refusing updates at the moment. In over a decade of Firefox use I'd never experienced such grief. I know you are better than this, but I'm having to use Edge in the meantime. I was unfamiliar with this website before because I never had problems. You may have solved some of these problems, but I still have some recurring with each update. Thank you for your consideration.
