unwarranted redirects and forgotten data entry

Firefox on android forgets where it is when it is minimized, or even on its own support page where it erases previously entered data fields if I click on any link on the support page! This is a major problem with banking websites. Example: I go to log on to my banking website which requires two Factor authentication. The phone call comes in with the authentication code and auto minimizes Firefox when the phone app launches. I go back to Firefox, and it has stepped back to full web pages back to the credentials entry page which requires another authentication call from the website! This leads to an endless cycle of redirects which cannot be circumvented currently. Firefox needs to remember AND STAY where it was with all entered field data; 1)when minimized, 2)when selecting an alternate tab or window, 3)when selecting an informational link on the date of field entry page (selecting an info link should not erase my data that I'd already entered), 4) when selecting the Share Data button on this very support page (which I can't actually use right now because it'll erase what I just typed when it tells me it can't access my data)
