"Change it to "Use custom settings for history" and then follow the following information and picture.

Deleting History/Lost History (Tools -> options -> Privacy), make sure you are not clearing in "Settings for Clearing History" anything but cache. The items you have check-marked there will be cleared at end of session if "Clear history when Firefox closes" is check-marked. If under tools you click on "Clear recent history Ctrl+Shift+Del" you should be asked for how much history to delete {1hr, 2hr, 4hr, today, everything} and what to clear in the details drop-down. Make sure when using the location bar you are displaying both "History and Bookmarks" so the AwesomeBar can look for items from both.

A possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.

Hello dmcritchie, thank you so much for your help and the kind picture. I followed your suggestion but unfortunately it didn't work. The down arrow in addressbar doesn't work. When I click on it nothing happens but the bar is blued-out. I forgot to mention that I use macbook and firefox 3.6.19.

Hello cor-el, first I read your reply I thought " this is too much for me, I am entirely ignorant about computer". But I struggled with the links you sent and somehow it worked. Thanks a lot!

You're welcome
