Had issue that when I went to put in a saved password in an address bar it would flicker or blink and could not pick ID I was trying to input , even when filling out forms and had to scroll to answer questions it would only flicker and would not show all the responses . Had to remove Fire Fox compltely and issue was gone when I used Safari

Quick question for you and for clarification, is the device with the issue a desktop computer or a mobile device?
Also if it is the desktop, please consider disabling each of the password manager add ons if there are any. Diagnose Firefox issues using Troubleshoot Mode
Else check if there might be duplicate entries for a particular site: Password manager - Remember, delete, change and import saved passwords in Firefox
