Yes. On Linux, where Adobe's Flash was piece of shit (sorry for the language but you can't describe it better), Firefox was using NSPluginWrapper for quite a some time. Similarly, Opera uses its own plugin wrapper. Both of these start Flash (and other plugins) in separate process so when the Flash crashes, it does not take down the browser. (Chrome has something more sophisticated I think)
