Opera introduces the looks and the performance of an exceptional Web browser.
Opera offers free and easy to download Web browsers for computers, mobile phones and devices.
New Features in this Beta:
Operating System Integration You use your operating system all the time, and need your browser to feel part of it. Opera 12.10 for Mac supports a number of new Mac OS X Mountain Lion features such as Notification Center and built-in sharing of content to social networks, and even comes with Retina Display support. Windows users aren't left out; as part of our continuing work on Windows 8 integration, Opera 12.10 beta has inertia scrolling and pinch-to-zoom on Windows 7 and Windows 8.
Opera 12.10 beta now supports International Color Consortium (ICC) profile v4, which will make photographs more vibrant and colorful, displaying them exactly as the photographer intended.
SPDY support Opera has always been about speed, so the new release incorporates the new SPDY protocol, which makes web pages load faster on SPDY-enabled sites such as Twitter, Gmail, WordPress and (soon) Facebook. For consumers, things will just work faster, but developers wishing to see which sites have SPDY support can download a SPDY indicator extension.
Extensions Talking of extensions, we've added several new APIs to give more power to developers. The most notable of these is the Context Menu API that allows an extension to add options to the user's right-click menu. Other improvements include the Resource Loader API, the Screenshot API and an update to our URL Filter API.
In order to ensure security for end-users, by default only extensions that are hosted by Opera may be installed, as these have been rigorously tested to ensure they're safe and don't harm a user's machine or data.
HTML5 and Web Standards Opera is the browser that began the HTML5 specification that is transforming the web, so it's only natural that we'd be adding more support for the latest standards.
Opera 12.10 beta adds partial support for the Fullscreen API that allows video, games or web pages to use the whole screen to remove distractions like browser chrome that can divert your attention from skateboarding kittens or shooting aliens. (We say "partial" because new "HTML5 the living-on-the-edge standard" specs chop and change. This beta implements the Fullscreen API editors' draft 7 February 2012, while the standard has now mutated in the latest July 2012 version.)
There's also partial support for the Page Visibility API that allows a tab to know if it isn't visible so, for example, it could suspend resource-hungry animations or pause HTML5 audio/video until the tab returns to view.
Now that security concerns with the Web Sockets spec are addressed, we've turned on this functionality by default in Opera 12.10 beta.
User-Agent string changes Opera 12.10 will ship with a simplified UA string. Firstly, we have dropped the "U;" token, which signified that the browser provides crypto support that is stronger than what the "international" builds of Netscape offered circa 1995. The second change is removal of the language indicator.
