The real world does not have broadband connections on every corner. When you enable Opera Turbo in Opera 10, it will use our powerful servers to compress Web pages, boosting and accelerating connections to a crowded Wi-Fi in a cafe or a tethered mobile phone. The new Opera Presto 2.2 engine in Opera 10 is up to 40% faster on resource-intensive pages such as Gmail and Facebook. In addition, with an Acid3 100/100 score, Web Fonts support, RGBA/HSLA color and SVG improvements, Opera 10 is ready for the next generation of Web applications. Opera 10 is created to use system resources intelligently and to give you the best possible performance on your computer. With an elegant under-the-hood architecture and a beautiful new skin by designer Jon Hicks on top, Opera 10 feels, looks and runs like a fine-tuned machine.

New in Opera 10:
• Opera Turbo for fast browsing on slow connections
Opera Turbo uses compression technology that provides significant improvements in browsing speeds over limited-bandwidth connections, for example, when using a crowded Wi-Fi in a cafe or browsing through your mobile phone while commuting.

• New visual tabs and sleek design
Opera has always been the pioneer for how to deal with tabs in your browser. In Opera 10, we introduce a resizable tab bar. Drag the handle underneath the tabs to reveal thumbnails of your open Web pages. And, because great features should come in beautiful packages, designer Jon Hicks has created a whole new look for Opera 10.
• Speed Dial your way
You asked for it! Customize your Speed Dial to fit your own needs. Click the Configure Speed Dial button and choose from 4 to 25 favorite Web sites for quick access every time you open a new tab. You can also add a custom background so that you feel right at home.
• Web integration
If you use a Web mail service as your default mail client, you can tell Opera 10 to do the same. Clicking on e-mail addresses or “Send by Mail” in Opera will open the compose page from your Web mail service provider. The same is true with the Feed reader — you can now also add any RSS/atom feed into your favorite online feed reader from within Opera 10.
• Resizable search field
Have a clearer view of what you are about to search by simply expanding the size of the search field — because many of life’s questions require more than two words of space.
• 40% faster engine and cutting-edge Web standards support
We optimized the new Opera Presto 2.2 engine in Opera 10 to be much faster on resource-intensive pages such as Gmail and Facebook. In addition, with an Acid3 100/100 score, Web Fonts support, RGBA/HSLA color and SVG improvements, Opera 10 is ready for the next generation of Web applications.
