Opera 11.11

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.
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.
Interface : Opera's interface keeps the same look that debuted in Opera 10.50, with a condensed menu button in the upper left corner, tabs on top, and a translucent status bar on the bottom that hosts buttons to reveal Opera's Panels, and to activate Link, Unite, and Turbo. The bottom right corner of the status bar sports a dedicated zoom button.
Buttons on the navigation bar have been condensed, and are now the same height as the location bar. This gives the interface a polished look, and minimizes the amount of space that the bar takes up. The search box, located in its default space to the right of the location bar, can be removed. That and further interface customizations can be made by right-clicking on the navigation bar and selecting customize.
Extension buttons appear to the right of the search box, as they do in Google Chrome, while a recycle bin for quickly re-opening recently closed tabs lives on the right side of the tab bar.
The influence of the radical interface changes that Google Chrome introduced in 2008 can be seen here, from the tabs on top to the extension icons, yet Opera's personality does still come through enough to have a different vibe and feel from Chrome.
Another change comes to the security badge system, which marks sites as "verified safe". Click on the gray "Web" globe icon to the left of the URL bar to check a site's status. Getting information returned was quick on most sites, although it was a bit slow for others. The badges are colored yellow for "secure", green for "trusted", and blue for when you're running Opera's Turbo mode, another excellent feature that's designed for assisting people surfing on slower connections. The Turbo badge will also display estimated data savings. You can turn on Turbo using the button in the status bar at the bottom left of the browser.
Opera's site badges also include a useful reporting mechanism, so it's easy to report a site as fraudulent or malicious. With plug-ins disabled, click the "play" triangle and the plug-in content--in this case, Flash video--will start playing.
