I see this kind of stuff when i accidentally leave firefox looking at a
munin graph page for the night. It seems to me that images you look at
never get released from memory or something. This has nothing to do with
npviewer.bin (part of nspluginwrapper) however.

Or try to remove nspluginwrapper or not use the flash plugin, which
seems to be the reason for a lot of performance problems as well. It is
also the flash plugin (maybe in combination with nspluginwrapper) that
was the reason for the youtube image, you could have removed it by
killing npviewer.bin
