How to clear auto suggestions when filling the same form


There is one form i repeatedly need to sign in.
It asks for a number
say the number is 123456

every i start typing the number 1 a whole loads of other numbers appear in a drop down menu.
These numbers are the times i filled the number wrong.
Some how the box in the form remembers these numbers and suggests them to me.
I want to delete them

How do i do that?

Clearing form filling information

You can delete the auto fill entry in about:autofill which will remove it permanently or you can set the autosuggestion items to be cleared upon close which will still retain the autofill entries saved in about:autofill but will remove all the saved items from that session

You can also select Autofill data which will permanently remove and will need to add each time


worked nicely.
