From that report:
Mozilla FireFox 2: Overall rating 5/5.
Firefox outstanding features include
pop-up blocking; a tab-browsing; integrated Google
searching; spell checking, anti-phishing and other advanced security features, simplified privacy controls that let you cover your tracks more effectively; a streamlined browser window that shows you more of the page than any other browser; automatic session-restore function and a number of additional features that work with you to help you get the most out of your time online.
The net result is that Mozilla Firefox is a complete, fast, full-featured Web browser that makes browsing more efficient than ever before.
Opera 9: Overall rating 3/5.
The motto of Opera has always been one: develop the quickest, smallest and most full-featured browser available! And the latest version maintains the tradition. Not only Opera 9.23 keeps safe all the basics (tabbed browsing, search bar, advanced bookmarks tools, and easy integration with your favorite e-mail client and chat provider, mouse-gesture support, keyboard shortcuts, and drag-and-drop functionality further enhance your surfing experience), but also pushes it to the top of the class with some innovative extra features.
Integrated theme support lets you preview themes from within the interface; Widgets are small. The Wand utility combines autofill with saved passwords. Opera comes with torrent support and real-time fraud protection for safer browsing. A new feature in version 9.2, Speed Dial, permanently assigns bookmarks and tabs any digit from one through nine. When you enter one of those numbers into the URL bar, the corresponding site loads when you hit enter.
Overall, I think Opera might have what it takes to unseat even the biggest-name browsers if users give it the opportunity. I especially enjoyed the Speed Dial feature. But in our opinion Opera has still to move a little bit forward if it wants to keep up with the best players, especially if we consider the user interface and the usability of the most advanced features.
I have my own rating based on a daily use of FF, IE and Opera.
Security is a very important aspect in that rating. IE is less secure, then comes FF and finally Opera that is most secure. Cross browser scripting is "impossible" in Oprea, and there is an extra layer of security if you use the browser on your bank account, the master password that is set in Opera. That rating will not be changed until I hear about a more secure browser.
P.S. Accessibility is much discussed on the internet. Why is accessibility no a part of that test?
