Have you ever mistyped and saved something in a form while using Firefox? How about submitting something on a form that you’ll never need to use again? When you go to enter information in a form, does it gives you a long list of suggestions, when you regularly only use one entry? As a regular user of products like Google Calendar I often have this problem. Here is a simple trick that will let you clear out the bad or outdated form entries, without clearing all of your form data.
Go to the form where the mistake is.
Put your cursor in the text entry widget and hit down until the incorrect entry is highlighted.
Now press shift + delete
It’s that simple. I hope this helps. Kevin
