Are you sharing your computer with colleagues, family, or someone you live with? Do you surf with Opera on publically accessible computers? This page holds some tips for maintaining your security and privacy within the same computer and user account.
First of all, when installing Opera on a multi-user Windows computer, make sure to opt for separate user directories during install. This will ensure that your settings, e-mail, passwords, history, and so forth, are stored in your own user directory only. Remember that this may be of little use if other users have administrator privileges on the same machine, unless you protect your files by other means.
When using Opera on a shared user account, for example in a library, the following features may raise privacy concerns, and you should consider whether you want to disable them, avoid them, or use them with caution:
All browsers keep records of where you have been on the Internet, and store data about the Web pages you visit in a local folder known as the cache and in your browsing history. If you are using a shared computer and do not want other users to know about sites that you have visited, you can use private browsing.
From the menu, select either "New Private Tab" or "New Private Window" depending on how you prefer to browse. When you close a private tab or window, all records of the Web sites you visited are removed; no record is kept in the browsing history, cache or Closed Tabs, and no cookies or logins are stored.
Caution: While private tabs and windows do not leave any record of the Web sites you visit, if you deliberately save data, for example, if you save a bookmark, or download a file, this will be still visible after the tab or window is closed.
To quickly close all the private tabs and windows you have open at once, select the tab bar and select "Close All Private Tabs" or use the Ctrl+Shift+Q keyboard shortcut.
If you do not use private browsing, you can useto completely clear the history, cache, and so on. Select "Detailed options" if you want to specify the items you want to clear. Note: Be aware that this clears the items competely for all users.
