If you’d like an open tab to be housed in a separate window, simply drag and drop the tab off the tab bar. When pinned, the tab will move to the left side of the tab bar where it can be accessed quickly. To pin or unpin a tab to the tab bar, Ctrl+click the tab and select Pin Tab/ Unpin Tab. You can prevent Opera from closing tabs accidentally or prioritize important pages by pinning tabs. To close all tabs, except your current tab, Ctrl+click the current tab and select Close Other Tabs. To close a tab, hover your mouse over the tab and click the X button.

Tabs allow you to interact with many pages simultaneously without closing a page until you are ready.
