Hmmm...  I have linux-f10-flashplugin-10.2r153 and it is installed 
as /usr/local/lib/npapi/linux-f10-flashplugin/libflashplayer.so, not 
in /usr/local/lib/browser_plugins/.  This definitely looks 
suspicious.

I must confess I've never tried it on STABLE/i386.  Will try on 
VirtualBox when I get back home.

Try "pkg_info -W /usr/local/lib/browser_plugins/libflashplayer.so" and 
see if it is stale.  If so, you can remove it.  Try "nspluginwrapper 
-v -i /usr/local/lib/npapi/linux-f10-flashplugin/libflashplayer.so" 
and see what happens next.
