The bottom line: Extensions, highly competitive page-load times, cutting edge features, and strong support for "future Web” technologies make Opera 11 one of the best browsers available.

Review:
The second-oldest browser currently in use, Opera debuted way back in 1995 and has recently undergone a major overhaul. No longer the quirky choice of enthusiasts, Opera has developed into a robust, full-featured suite of browsing tools.

Opera covers the basics with tabbed browsing, mouse-over previews, a customizable search bar, advanced bookmarking tools, and simple integration with e-mail and chat clients. Mouse-gesture support, keyboard shortcuts, and drag-and-drop functionality round out the essentials.

No longer a fledgling upstart, Firefox is the gold standard of alternatives to the still-dominant Internet Explorer. Firefox 3.6 is full-featured, lightning fast, and secure. Its killer selection of add-ons remains strong, with built-in support for the next generation of themes, called Personas, plus the latest update makes version 3.6 about 20 percent faster than version 3.5. However, competition is strong and it can no longer be said that Firefox is the fastest browser available.

Internet Explorer 8 addresses just about all of the major concerns that users and critics have had with the world’s most used browser. Whether they get answered in a way you like is another matter.

There are several new and interesting features. Web Slices lets you save predefined sections of a Web page for at-a-glance viewing. Instead of going to a traffic Web site for updates, the latest commuting news comes to you. Similarly, Accelerators make repetitive tasks one-click behaviors, for instance finding directions or blogging. InPrivate browsing introduces a cache and history on-off switch, while related tabs are color-coded and automatically reorganized as you open them. There’s also tab sandboxing, which means that when a tab crashes, IE itself won’t, and it even tries to resurrect the page that crashed.

The bottom line: Google Chrome 10 comes with a full range of competitive features, and is among the most standards-compliant and fastest browsers available. It lacks some of the fine-tuning customizations in Firefox, but Chrome’s minimalist interface, fast page-load times, and support for extensions make the browser appealing to the average user as well as to Google fanatics.

Review:
Google Chrome continues to mature from a lightweight and fast browsing alternative into an innovative browser that’s also on the precipice of a potential browsing revolution with the pending Chrome OS. The browser that people can use today, Chrome 10, offers highly competitive features including synchronization, autofill, and standards compliance, and maintains Google’s reputation for building one of the fastest browsers available.

The previous version of Safari for Windows dramatically changed the nature of the browser from something of an unfinished curiosity to an alternative with seriously quick chops. It lacked many of the customization features that define most other browsers, but certain unique default features, such as the visually impressive, Cover Flow-inspired Top Sites and history viewing, made it worth checking out for more users besides just browser enthusiasts and jaded reviewers.
