Since the most recent updates of Chrome, npviewer.bin is no longer listed in the process list when a flash content is loaded.

What process does Chrome use now?

** EDIT **

This is Google Chrome 17.0.963.56, and I usually

  1. kill the process when it uses too much memory or
  2. invoke scanmem on it to search for some values

(1) What were you trying to do with that process? (2) Are we talking about Chrome or Chromium? (3) Which version of chrome/chromium (tool menu button > about chromium)? – medigeek Feb 18 '12 at 22:45
question updated. – Yanick Rochon Feb 18 '12 at 22:54
Perhaps if you install the nspluginwrapper package it will start using it again. I'm not sure though. :) – medigeek Feb 19 '12 at 11:15
And why would I do that? I usually follow the simple of rule of : "If it ain't broken or doesn't need maintenance/upgrade, don't touch it." It works fine now. :) – Yanick Rochon Feb 19 '12 at 11:32

npviewer.bin isn't part of Chrome - it's part of a compatibility wrapper called nspluginwrapper that makes it possible to use the 32-bit Flash plugin (and other 32-bit plugins as well) in a 64-bit browser. To 64-bit Chrome, nspluginwrapper "looks like" a 64-bit Flash plugin. But so does a real 64-bit Flash plugin, which is preferable, so I'd guess that you recently got such a plugin and thus Chrome is no longer using the nspluginwrapper version. Have you got a chrome --type=plugin process? It's been there the whole time, but with nspluginwrapper, it's just a proxy for the real plugin that runs in the npviewer.bin process. For a native 64-bit plugin, the plugin itself runs there.

oh! wonderful! indeed, there's a --type=plugin --plugin-path=/usr/lib/flashplugin-installer/ process. Thanks! – Yanick Rochon Feb 20 '12 at 1:48
