Well, I have this working, except...

I found in the discussion at
https://kde-apps.org/content/show.php?content=125066&forumpage=2 that 
you can have a file ~/.kde/share/config/kpartsplugin-mimetypes.rc where 
you can blacklist mime types. So, I listed all the  mime types that 
firefox was using kpartsplugin to handle and blacklisted them all except 
application/pdf.

That works, and hopefully I can find the equivalent place for that file 
so that these settings can be picked up systemwide.

The only problem now seems to be that after opening a pdf file I see 
that plugin-container is running at 100% cpu.

Curiously, the first time firefox loads the pdf I momentarily see a page 
with what looks like a menu structure of mime types. Then its 
overwritten by okular displaying my pdf.

Anyone got any idea whats going on here? Maybe this is whats causing 
plugin-container to go 100% cpu.

It would be great if someone could verify this behaviour - maybe its 
some of my customizations that provokes this.

Thanks
