Opera for Windows, OS X, and Linux 64bit test ” version released of Opera 12. Also, the browser now on all the operating systems support it out-of-process to run plugins so the stability would improve.
The out-of-process method are browser plugins in a separate process turned. If the plugin crashes, it is no longer the entire browser also undermined. This mechanism is already in browsers such as Firefox and Chrome, but, until now, had the Opera only in its Linux – and FreeBSD-based versions of plugins in a separate process to run. With the new test version of Opera 12 is the out-of-process to run plugins, now also available in the Windows – and OS X-version.
Opera 12 for Windows, OS X and Linux are now also available in a 64bit version. According to the Norwegian browserbouwer perform the 64bit-versions, in certain cases, better than the 32bit editions and Opera 12 would have more opportunities to allocate memory.
Opera says that there deliberately is waited with the release of a 64bit version until the out-of-process mechanism worked entirely. This allows the browser 32bit plugins to run, an important property because for a lot of plugins still no 64bit version exists.
