If you aren't aware of what OOPP is, it stands for Out of Process Plugins, and is a technique adopted by some browsers to protect the browser from crashing when a plug-in crashes.
This isn't the only good news though, as these new Opera Labs builds also tout support for OOPP (Out-of-process Plug-ins).
