Opera is a browser released by Opera Software and is completely free. This browser is known for its SpeedDial panel, as well as its mini version for phones - OperaMini and OperaMobile. Mini is very popular in Europe and occupies a good market share due to its "non-gluttony" traffic, which is appreciated by EDGE Internet subscribers. The desktop version of Opera has its own peculiarities.
A new feature in modern browsers is tabs. Previously, their function was performed by windows, i.e. each time a new link was opened, a new window was created. Closing tabs in Opera is as easy as closing a window. To do this, find the tab bar. It is located below the main menu (in older versions) or at the top of the window (in newer versions). Next to each tab is a cross-shaped icon, when you click on which, the tab will close. You can also close the tab by clicking RMB (right mouse button) and selecting "Close".
When you have many tabs, in order not to close each one in turn, right-click and select "Close All". If you only need the tab that is currently active, call the context menu (right mouse button) and select "Close all except active". Accidentally closed tabs can be returned by clicking on the trash can icon in the upper right corner and selecting the desired tab.
There are two other types of tabs in Opera: private and locked tabs. The first kind of tabs will help you stay anonymous online, i.e. history, passwords, cookies are stored while this tab is open. When you close it, all information is deleted and cannot be restored. This type of tabs are closed in the usual way. But the second type of tabs closes differently. Locked tabs cannot be closed until unpinned.
To unpin a tab, open the context menu and select the "Lock Tab" item. Now a cross will appear next to the tab and it can be closed using the methods suggested above. It is worth noting that when one of the tabs is fixed and you click "Close all" or "Close all except the active", then the fixed tab will not close.
