Opera says the new browser features Opera Turbo technology to deliver web content up to 40 percent faster than its previous browser Opera 9.5. The function will also automatically switch on if a slow connection speed is detected.
The web browser also features a resizable tab bar, which when pulled down reveals thumbnails of every open tab in your browser window.

Opera also expanded the inline spell-checker to support 51 languages and revamped the user interface, with a new design from Jon Hicks.
"Initially, we were just going to clean-up some elements and focus on the interface for new features. But, over time, the new user interface elements became so different that we decided to update everything," said Jon Hicks.
"We think Opera 10 will redefine how you can enjoy the web. We have more surprises on the way, but when you try the features, enjoy the acclerated performance and get a glimpse at our shiny new wrapping, I think Opera 10 beta will excite both long-time users and those new to Opera," said Jon von Tetzchner, CEO, Opera Software.
Opera 10 can be downloaded from Opera's website for Windows, Mac and Linux.
