Updated to nightly 10. In the address bar/search; i begin typing url when using the down arrow on keyboard, the autofill chooses the last entry rather than the first entry immediately below. Drop down within websites are fine the pattern i found is down arrow - Last entry down X2 - first entry on the last "page" drop down list page down X3 onwards - first entry on the second last page of drop down list until the first entry Tried disabling and enabling Hardware acceleration Tried in safe mode
