When surfing the net, websites will leave little bits of information, known as cookies, stored on your PC. These cookies allow your browser to remember your login details or site preferences. It's very easy to enable and disable them. We've already shown you how to do it in Firefox 5, Internet Explorer 9 and Google Chrome but it's slightly different to implement in Apple's Safari. Here's how.
Ensure your login-details are stored by your browser
Open Safari, and then using the icon that looks like a cog, open the settings menu and Select Preferences.
Select the Security tab from the top of the window and next to Accept cookies, make sure the box entitled Always is ticked.
Alternatively, if you want to disable cookies check the box next Never.
