What’s new

Opera Turbo for fast browsing on slow connections

Ever felt a Web site was loading slowly? Do you think it will happen again? Think again: Opera Turbo is a compression technology that provides significant improvements in browsing speeds over limited-bandwidth connections like 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: world famous designer Jon Hicks 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. Hit the configure 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 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 the 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 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 beta is ready for the next generation of Web applications. Learn more…

More new features in Opera 10

Inline spell-check

Write freely in your Facebook wall, blog or Web mail. Opera 10 beta underlines any misspelled words, so you can express yourself without reservation. By using the popular Hunspell dictionary format, you can be sure you’ll always have the most complete and updated list of all languages.

Auto-update

Opera 10 beta makes it easier than ever to stay up to date with the latest version. With Auto-Update you will be able to choose completely automatic updates or have the option of being notified when an update is ready to install. As always with Opera, it is your choice.

E-mail your way

Opera Mail can now send rich text messages including inline images, styled text, links, and/or custom HTML. You can also delete emails from your POP server after a determined amount of days, so can keep under control of your Web space.

Automated Crash Reporting

Opera is designed to restart and recover all your tabs if a crash occurs. But, now you can easily send us a crash report to help us continue to make Opera the most stable browser around.

Opera Dragonfly evolved

Our Web developer debugging tool is now even better, allowing you to edit the DOM and inspect HTTP headers.

Thanks for trying Opera 10 beta!

Opera 10 Beta 1 more details:

As always Opera desktop team have some new goodies for you, things you have not seen in previous snapshots.

Visual Tabs – oh shiny!

Opera desktop team have added thumbnails on the tabs themselves to make it even easier to find that Web site you were looking for. These visual tabs are currently folded away by default, but can easily be enabled by dragging the drag handle available just beneath the tab bar.

Double-clicking or middle-clicking the same drag handle will show/hide the tab thumbnails.

Speed Dial – more shiny!

Two popular requests for Speed Dial has been to be able to use more than 9 configured sites. We’ve also seen frequent requests to be able to have a customized Speed Dial background. Well, guess what?

In the bottom right of the Speed Dial you now have a new Configure Speed Dial button that opens a brand new configuration dialog.

With this new configuration dialog, you will be able to set a background picture that can be stretched, centered or tiled. It is also possible to set the number of sites that should be shown, ranging from 4 to 25.
