Opera introduces the looks and the performance of an exceptional Web browser.
Opera's user interface has received a major overhaul with the new start-up dialog, and new default buttons, skin and panels in a blue and white color scheme that can be changed back to classic Opera look or another design. At start-up you can select a single or multiple document interface (SDI/MDI).

Opera is a standards-compliant Web browser for Mac OS X, Unix, Windows,QNX, Symbian, OpenBSD and several other operating systems. Opera gives you a better Internet experience with its combination of speed, unique features, and keyboard shortcuts.

Opera for Mac is available for free in an ad-sponsored version, or without the ads through a paid registration.

It offers Mac-specific features such as keychain access in forms and a cookie manager. It is also the first Mac browser to be available as a shared library. Application developers can now include the Opera shared library inside their applications.

Here are some key features of "Opera":

· Fresh new look
We've cleaned up our front yard. The Opera interface is designed to make the advanced functions easy and effective to use. Menus, toolbars and other elements have undergone our "slim and clean"-routine. The licensed version has the largest browsing area in the industry.

· Security
Stay away from spy-ware, viruses, and other malicious applications that silently attack your computer while you are surfing the Web. For example, Opera displays security information inside the address bar, located next to the padlock icon that indicates the level of security present on a site. Opera 8 also provides protection against phishing attacks and automatically checks for security updates. More about security

· Speed
We're holding on to our claim: "The Fastest Browser on Earth". In Opera 8, further improvements have been made in the way the browser reads pages to allow you to fly the Web.

· Tabbed browsing and pop-up blocking
Opera pioneered tabs and pop-up blocking ages ago. But they're still key features that more and more people start enjoying. With tabs you can open multiple pages within the same application window. Opera lets you control whether to block all pop-ups, or open only the ones that you have requested.

· Integrated search
Search your favorite sites, for example Google, eBay, or Amazon without having to go to their Web pages. Use the integrated search window or search directly in the address field using shortcuts (e.g. writing "g Opera" in the address field will search for "Opera" using Google).

· Customization
Using the 'appearance' dialog you can make Opera look almost any way you want. Move buttons and search fields, add and remove toolbars, and so forth. Opera skins can change the look of your browser by giving it the icons and buttons of your choice.

· Password manager
Opera's password manager, the Wand, remembers your usernames and passwords so you will not have to. The password manager can store more than one username and password combination for each page, and will let you choose which one to use if multiple combinations are stored.
