Under Firefox, I allow some type-in boxes to provide previously used entries. For example, in the NOAA weather pages, the entry for location has built up a list of cities and towns I've entered. The problem is there are some typos and some places I just don't need. Is there a way to remove single items from these lists? I tried highlighting an entry and hitting the backspace key. No luck. Swiping doesn't help. Trying to select a whole word and cutting doesn't work. What does work?
