Cookie tips

Cookies are pieces of information stored in files that webservers store on your computer when you are browsing. These files allow these servers to recognize your computer the next time you visit their sites, often to improve your browsing experience. They cannot cause direct damage to your computer system in any way, but they can record your browsing habits in an intrusive manner and trace your movements across different websites.

For example, some sites use cookies to store your username so that for 10 or so hours after you log in with your password, you will not have to re-type your password again. This is a convenience, but it can also be a security hazard if others have access to the computer you are using.

Another use of cookies is to store information about the pages in a site that you have visited previously. This allows a website to customize itself with fresh content, rather than showing you the old material, and to present you with content you might be interested in based on what you have already viewed.

Opera gives you specific control over what cookies to accept and reject. Here are some tips to help you control your cookies.

Opera allows for a wide range of cookie setups. The options are:

Accept cookies Allows all cookies to be stored on your computer

Accept cookies only from the site I visit Allows only cookies that are set by the website you are visiting to be stored, not those set by any other sites whose content is displayed in frames or via images on the current page

Never accept cookies Refuses all cookies to be stored and refuses to use existing cookies; by checking this option, you may have difficulties logging on to a significant number of websites

Delete new cookies when exiting Opera Deletes cookies that have been added after this preference was enabled when closing the browser

Ask me before accepting cookies Provides a prompt every time you receive a cookie, allowing you to decide on each one individually

You can also configure cookie settings when you are viewing any site by going toSettings Quick Preferences Edit site preferences Cookies.

If you want to enable or disable cookies quickly, from the menu selectSettings Quick Preferences Enable/Disable Cookies.

Selecting Manage Cookies in the Cookies preferences tab allows you to add new domains, delete cookies, and edit cookie settings specifically for each server. The Cookie Manager displays, which lists all the domains from which you currently have cookies.
