nspluginwrapper is a proxy plug-in and viewer for NPAPI browser plug-ins. It allows browsers to run foreign plug-ins built for a different architecture, most commonly to run a 32-bit plug-in in a 64-bit browser. This is needed by 64bit midori compiled against GTK3 to use the flash plugin: cd /usr/lib64/mozilla/plugins nspluginwrapper -v -a -n -i libflashplayer.so
