I've never tried using external filters, so I'm not going to be a
whole lot of help but
https://www.privoxy.org/user-manual/actions-file.html#FILTER
  (Note: as of version 3.0.3 plain text documents are exempted from
filtering, because web servers often use the text/plain MIME type for
all files whose type they don't know.)

Have you added
debug    64 # debug regular expression filters
to the config file to see if privoxy tries to run the filter?

If the filter isn't being called, maybe you need
https://www.privoxy.org/user-manual/filter-file.html
  Enabled content filters are applied to any content whose "Content
Type" header is recognised as a sign of text-based content, with the
exception of text/plain. Use the force-text-mode action to also filter
other content.

It's a user-defined alias
