When I am having an OpenShift 3 Server Adapter in Server view e.g. freshly created, it is stopped by default. Its context menu Show In - Web Browser is disabled at this point, although it not makes much sense, because it is possible to show an application in browser at this point via OpenShift explorer view. Adapter does not have to be started to perform this. Max suggested that after selecting context menu Show In - Web Browser, an OS 3 server adapter could/should start.
