Firefox does not recognize mime type of pdf documents

Firefox does not recognize the correct mime type of pdf documents in my wiki. Not only my Firefox. The Firefox of my colleagues as well. And it is not a general Firefox-PDF-issue. When I open other web pages with PDFs on them, they are being handled correctly. Just not on my foswiki site.

PDFs are displayed as Code, as plain text.

When I open the same foswiki pages or document attachments with the Internet Explorer, they look OK. Pdfs can be clicked or happily appear inside of their iframes.

My Foswiki installation is sitting on a debian server with a standard apache installation.

I'm using ssl (self signed key) and LDAP authentification via Apache, and that's all that is special about my configuration.

Symbolic links to mime.load and mime.conf are sitting in my mods-enabled directory, /etc/mime.types contains an entry for pdf files and is being used in mime.conf like this:
TypesConfig /etc/mime.types

Also, I tried to add a mime type for pdf manually in my VirtualHost section:
AddType application/pdf .pdf

Still, firefox displays garbage instead of PDFs. What did I miss out?

Narf. OK, got it. Somehow, I don't know why and how, the data/mime.types file got garbled. Completely. It looked like the source of a normal foswiki topic file. I can't remember ever touching this file in any way.

I found a suitable file on github and copied the contents from there:

Problem solved.
