How to replace default debian 5 flash installation?

How do I replace the default debian 5 flash installation with the adobe version?

I enabled contrib and non-free repositories in the sources.list file. And installed flashplugin-nonfree.

Logged out and back in, firefox still uses the default one.

I tried removing swfdec-* but that asks for gnome to be removed as well.

• Try running update-flashplugin --install and see what the output is.

  Also, look into /usr/lib/iceweasel/plugins and perhaps you can manually remove something if all else fails.

  What's in about:plugins ?

• update-alternatives --config flash-mozilla.so will allow you to select which Flash plugin is used.
