Hi Chris, I have a guess.

Separate from saved logins, Firefox has a feature that remembers form and search history. Three notes:

(1) You can remove individual form history items by pressing the down arrow to highlight an item and then either Delete or Shift+Delete (depending on context and OS?).

(2) You can set Firefox not to store ANY form or search history (selecting that will also suppress the suggestions). Unfortunately, there isn't a way to say "not emails" or "not on this site."

More info: Control whether Firefox automatically fills in forms

(3) This is separate from the address autofill feature, so you can still use address autofill even if form and search history are turned off (if you are in a supported country).

More info: Automatically fill in your address on web forms

Hi jscher,

thanks for your feedback!

(1) I use macOS Sonoma 14.6.1 Unfortunatley i only can select a username but not delete it. If i select with arrow or just by clicking into the username field, the selected name is highlighted grey. But neiter "delete" nor "shift delete" do work.

(2) Thanks for this information but it does not solve the problem. I would like to use this feature. If i type in the field by mistake "Petre" instead of "Peter" i do not want to always have to choose between these both names. I want to delete "Petre" and only have the option to select "Peter"

(3) Thanks for this information as well but this is another topic i think. Isn´t it?

Did not thank that this is such a tough one. Did you try it yourself? You type something wrong, ths system grabs the wrong name and continuously presents it as an option to select.

Any other Ideas? I use Firefox 133.0

Best Chrsi
