In order to have a better browsing session it has built in a Trash Can where it places a closed Web page if you accidentally close a tab. It comes with a very good tabbed browsing engine, mouse gestures, a very good password manager and my favorite feature: the possibility to save the browsing session. It still has the features that were implemented in the previous versions of Opera. Since a certain minor version of Opera 9, the developers introduced the Speed Dial functionality which can be used in order to quickly access some predefined Web pages. This version comes with the possibility to add your favorite search engines. It has built in the widgets support, a BitTorrent client, a thumbnail preview when you hover over a browsing tab, a site preferences engine and it has also an improved rich text editing features. The 9th version comes with a lot of new features and it is a real upgrade if you are still using Opera 8.
Opera is an Internet browser and it has built in a lot of tools in order for you to have a safe and easy browsing session.
