Which flash do you have? the flashnonplugin-free package or gnash or swfdec.

Look into firefox and put 'about:plugins' without the quotes in the URL .

The first thing you will see are of flash.

This is mine.

Shockwave Flash

    File name: libswfdecmozilla.so
    Shockwave Flash 9.0 r999

MIME Type Description Suffixes Enabled
application/x-shockwave-flash Adobe Flash movie swf Yes
application/futuresplash FutureSplash movie spl Yes

As one can see from the filename its swfdec-mozilla which I'm using.
