Apple releases Safari 5.1.4 -- get it NOW!
In the field of security, the Remove All Website Data feature has been fixed so that all data is actually removed when this option is selected -- and Private Browsing has been enhanced. Now if you visit a site in Private Browsing mode that you have already visited in the regular way, any cookies that have been created can be accessed and made use of -- of course, no new cookies are created to maintain your privacy.
There are also fixes for a number of other problems that have emerged in previous versions of the browser including a bug that caused screen dimming when watching HTML5 videos. Other bug fixes include better performance and stability when extensions are in use, problems with screen flashing when switching Safari windows, and issues that prevented the pressing of US Postal Service shipping labels and embedded PDF files.
