Opera is an Internet browser with a pop-up blocker, multiple-windows navigation, mouse gestures, keyboard shortcuts, e-mail client with Spam filter, and integrated search all for user security and speed.

The cross-platform browser includes a multitude of other functions such as integrated built-in e-mail client, IRC-compatible chat, support for RSS newsfeeds, password manager, one-click customization and privacy protection settings.

Mouse gestures and keyboard shortcuts allow for accelerated Web navigation while the Fast Forward and Rewind buttons ease browsing. Users are able to run multiple windows as well as personalize the user interface with one-click skins.

The browser also contains special elements for users with disabilities, drag-and-drop support, a notes function, user profiles, and a host of other features. Opera supports the latest in security and provides password and cookie managers. If you have already installed Java, you can download the smaller non-Java version.

Opera's new looks are complemented with exciting features such as the Personal Bar and Pagebar, hotclick, improved window handling, bookmarks search, redesigned preferences, new shortcuts, extensive drag and drop, and support for Unicode and LiveConnect.
