Some sites' search fields will retain entries you've made in the past when AutoComplete is active. Try explaining why "divorce law" pops up as a possible match when your spouse uses HotBot for a search of his own.

Click the AutoComplete button in the Personal information section and uncheck the Forms box in the AutoComplete Settings dialog.
