Mozilla has released Firefox 3.6.11, a minor update to the open-source Web browser. The update addresses both security and stability concerns—including some potential security threats that could allow an attacker to take control of your computer. One additional Mac-specific fix in this version of Firefox restores the capability to use the Return key in the search or location bar when an input field on a Web page is focused. (Free, 17.6 MB)
Since this update I have lost all History. Specifically the Show all History page is blank. I have no clue what to do about it.
