Telling Edge not to fill out multiple fields

(Note, I posted this already, saw the delete icon and was curious what would happen if I pressed it, as I thought deleting threads had been disabled. It deleted my thread, which I didn’t think it would actually do.)

Since forever browsers have had a feature where it remembers what you typed into a particular field and will then offer it as a choice if you do it again. Recently Edge has taken it on itself autofill all related fields; I choose my email address from a dropdown menu and Edge fills out my name, DOB, address etc. Is there any way to keep the memorised data, but tell Edge to only ever fill out one field at a time, not to fill out the other fields?

Permit me to add a related question, if I may:

If I’ve filled in a particular field in two or more different ways on different occasions, and then I begin to type an entry in that field on another occasion, I get an immediate drop-down menu showing all the matching ways I’ve completed that field in the past. But one of the ways was a typo that I made, and I’d like to delete that from the list. How do I do that? (Browser in question is a somewhat-older version of Firefox.)

You can’t tell Edge anything (just ask Bono).

I’m not sure if it works in Firefox, but I applied this method for such lists in different browsers successfully: scroll to the item you want to delete from the list, right-click it and pray that a context menu with the option “delete” appears.

Since I posted this on Christmas Day evening US time, I imagine it disappeared before a lot of people saw it, so I’m giving it one bump.

I just thought of another possible method: scroll to the item until it’s highlighted and press the “Del” key. Should also work.
