I work with senior citizens and some people with disabilities. I am trying to support them and simplifying everything as much as possible. One woman only has use of one arm and one finger. She now uses 1Password she prefers Firefox. I cannot figure out how to enable auto fill features for her account verification request requests from email (yahoo) and iphone messages. Also, I want her personal contact info to autofill (we did fill out her contact card in Apple contacts. She uses a Mac desktop. Does something have to be enabled on each device or just within Apple and Firefox? I do not want Mozilla to fill in Passwords because we’re using the 1Password. I am confused about what to enable on the iPhone settings and what to enable on the mozilla browser. Apple refused to help me with Firefox features. Please help.
