Opera is the only browser that supports a site by site Management compared to other browsers. In Opera, if you click on Tools > Preferences > Advanced > Cookies > Manage Cookies, you will get access the “Server Manager” window showing you a list of all the websites that you browsed with Opera since it’s first install.
This Module does not only allow you to manage the way Opera accepts Cookies, but mush more than that. If you click on a website and than on the Edit button, the Site preference window will show up. This window contains multiple tabs so as to furthur customize the way Opera is going to load these pages.
The “General” Tab is where you can customize weather Opera should allow the page to show “Popups”. The “Cookies” Tab gives you a more advanced view of the cookies that the website has transacted with you. This page asks you either to allow cookies , allow only form that website or not to accept anything. Below, you can get a listbox of all the cookies that that specific site has shared with you. If you double-click on one of them, the “Cookie Information” window appears and gives you all the information about that cookie, such as expiry date, the value that it stores, and so on.
Finally, we have the “Network”, where we can customize “Automatic Redirection”, “Referrer logging” or “International Web Addresses in UTF 8”. However, the most powerful option is the “Browser Identification” where we can configure how Opera will Identify itself in it’s User agent String.
