Opera has introduced its Opera 12.10 beta browser for Windows, Mac and Linux. In an official statement, the company adds that the new version comes with even more browser goodies to explore. 

Developers can now allow their extension to work with Opera’s context menu, known as the right-click menu among friends. By allowing this, users can highlight text and make use of the extension for social networking, translations, and more. While screenshots can be tricky and difficult to share, Screenshot API developers can integrate a screenshot feature in their extensions and easily allow Opera users to share what they see in their browser.

You can now allow Opera extensions to load the CSS or JavaScript included inside an Opera extension file for easy manipulation of both functionality and design on web pages. For example, you can replace all fonts in Comic Sans on web pages to Helvetica or execute advanced JavaScript right inside webpages.

Among other things, Opera adds that it has tossed in more web-standard support. The Fullscreen API, along with the Page Visibility API, lets developers have more say in presentation of content and better manage resources in the browser.

For developers yearning to get going with Web Sockets, Opera claims to have some good news. Opera 12.10 includes the latest Web Sockets implementation with richer functionality for developers and an improved experience for end users, enabled by default

Among a long list of speed and performance improvements, Opera is introducing the SPDY network standard as a supplement for the HTTP protocol. In Opera 12.10, SPDY is enabled by default and works with webpages that support the standard. As of today, several large-scale websites such as Twitter and Gmail support the SPDY standard in addition to the traditional HTTP protocol.

“During the planning of Opera 12.10 we listened to the web developers,” says Krystian Kolondra, SVP Desktop, Opera Software. “The web developer community is thriving like never before and we want to support that in every way we can. With the new APIs, developers are better suited than ever to create extensions that give users of Opera for desktop a unique browsing experience.”

In both the Windows and the Mac worlds, there are new and exciting operating system updates this fall. With the launch of the Mac OS X Mountain Lion, a number of new features have been included directly in the operating system. Opera 12.10 for Mac supports a number of the new MacOS X Mountain Lion features, including Notification Center, Retina Display support and built-in sharing of content to social networks.

Soon, the Windows 8 version will also be publicly available, and Opera 12.10 includes updates to accommodate Windows 8 enhancements. These include touch support for Windows 8 Classic mode, with the added bonus of working on Windows 7, as well.
