It actually works now, for some plugins! Before I was only trying to get the rhapsody plugin to work, but this time I tried the flash plugin, which worked.
Instructions to install:
1) Download the Plugin and the Viewer from
http://www.gibix.net/dokuwiki/en:pro...spluginwrapper
2) Install Alien, if not already installed.
3) Convert the downloaded rpm's to deb's (sudo alien -d *.rpm)
4) Install the newly created debs (Install in this order: sudo dpkg -i nspluginwrapper-i386_0.9.90-2_amd64.deb, sudo dpkg -i nspluginwrapper_0.9.90-2_amd64.deb) -- If I got the order wrong, you'll know because it won't install.
5) Download the plugin you want to install, and extract the .so file. For example, to install flash, grab the tar.gz file from Macromedia's website, and extract libflashplayer.so.
6) Move the plugin (example, libflashplayer.so) to /usr/lib/mozilla/plugins. This is where nspluginwrapper stores the main plugin, so it's probably a nice folder to keep them.
7) Now we need nsplugwrapper to make the new plugin, so call: /usr/lib/nspluginwrapper/x86_64/npconfig -i /usr/lib/mozilla/plugins/libflashplayer.so (if wanting the flash plugin, of course). Depending on whether or not you run that command with sudo, it will either end up in /usr/lib/mozilla/plugins, or ~/.mozilla/plugins. If you ran it as sudo, you'll need to link it to either your profile's plugins or the main plugins (/usr/lib/mozilla-firefox/plugins). Or copy, doesn't matter. The old plugin must not move, as it's path seems to become hard coded in the new plugin created (which has "npwrapper-" prepended to the old name).
I had one issue where the npviewer.bin executable did not quit with firefox, so firefox couldn't load my profile again until I killed npviewer, but I'm not sure how I caused that. It happened another time, but I didn't see npviewer as active, so I had to logout. Macromedia flash worked, but the menu text didn't exactly show up for Google Videos, or the flash settings, though the main flash menu worked.
Oh, and if anyone gets the rhapsody plugin working for x64, let me know!
