Can the autofill sort be changed? Sorting by date>newest first.

I enter the same info into a website each day and it is a variation of the previous day's info. I made a change to the about:config on my previous install of Firefox. I was previously able to type the first two letters and then arrow up and the most recent was listed and could be entered into that field. I thought this was the setting listed as browser.formfill.bucketSize, so I changed it to 3, but it still loads chronologically newest at the top. I'd like chronologically newest to be at the bottom. Stupid, right? == This happened == Every time Firefox opened == Upon install
