When I click on 'History' >> 'Show All History' it is blank; I cannot go back into my history.

Okay. There are really two problems I've been having. 1. When I do the above-mentioned task, I have no history. when I click on History, it will give me 10 most recently visited websites, as well as the option to Show All History. When I click on Show All History, the box that pops up is completely blank. Other than my 10 most recent sites, I have no idea what websites I have been visiting. 2. If I try to bookmark a page, and then I click on the folder menu, and select 'Choose...', it goes blank. It does not show the dozens of bookmark folders that I have created for myself. Both of these issues are extremely frustrating for me. Any help will be greatly appreciated.
