My top 8 most visited sites stop working. When you open new tab it takes you to the top 8 most visited sites!! Now for some reason the most visited sites are not appearing in the top 8 most visited sites when you open a new tab. I tried clearing the top 8 most visited sites so it is empty and gone to some web sites a lot in week but for some reason it is not appearing in the top 8 most visited sites. And when I open a new tab it just empty. Sites are no longer being added. Other issues are when I click on history,show all history and last 7 days It does not show the day or time!! Like April 8 at 4:42PM Not sure if this is issue or firefox 33.1.1. does not display info like that. Note it is old Macbook pro 6 years old running Snow Leopard , Firefox 33.1.1.
