599. Briefly: Suddenly bankid doesn't work/wont be recognised.

The system: firefox 31, nspluginwrapper 1.4.4, debian wheezy, amd64

I've used bankid with Swedish banks in the past. Right now I'm running into trouble though. When clicking on the login button on the bank website I'm taken to this page:

Starting firefox (v31, but the symlink is called firefox25) from the terminal to catch the error messages I get

The solution was to do

/usr/lib/nspluginwrapper/x86_64/linux/npconfig  -a -v -u

Auto-update plugins from /usr/lib/mozilla/plugins
Looking for plugins in /usr/lib/mozilla/plugins
Auto-update plugins from /home/me/.mozilla/plugins
Looking for plugins in /home/me/.mozilla/plugins
Update plugin /home/me/.mozilla/plugins/npwrapper.libplugins.so
  nspluginwrapper ident mismatch, reinstalling plugin
Install plugin /usr/local/lib/personal/libplugins.so
  into /home/me/.mozilla/plugins/npwrapper.libplugins.so

as described by the nspluginwrapper maintainer (David) in a reply on http://www.geeklab.info/2011/11/reconfigure-nspluginwrapper/
