No guarantees, but it may have history from that far back. To check to see if your computer has history going back to July 2010, in the Bookmarks menu select "Show All Bookmarks" to open up the bookmarks library. In the library, in the left hand column it will show time periods to view history, if old data is there you should see an entry called "Older than 6 months", click on it. You can then scroll down through the history, checking the "View Date" column to see if you have history from July 2010.

How can I see history from 8 months ago??
