How to give a profile a default mimetypes.rdf file?
Hello,
I'm deploying Mozilla Firefox 31ESR on thousands of computers. I'm looking for a way to pre-configure how firefox handle the mimetypes. For instance, to open pdf with Adobe Acrobat Reader.
To achieve this, I put a mimetypes.rdf file in "C:\Program Files (x86)\Mozilla Firefox\browser\defaults\profile". When the profile is created, this file is copied, then modified.
The lines:
<RDF:Description RDF:about="urn:mimetype:handler:application/pdf" NC:useSystemDefault="true" NC:alwaysAsk="false" />
Becomes:
<RDF:Description RDF:about="urn:mimetype:handler:application/pdf" NC:handleInternal="true" NC:alwaysAsk="false" />
-If I replace manually the file "mimeTypes.rdf" in the newly created profile, it works perfectly.
It seems to be the same problem as: https://support.mozilla.org/fr/questions/1015378
Why is the mimetypes.rdf file modified? How can I set a mimetype policy?
Thanks a lot!

Sorry, I meant the line:
<RDF:Description RDF:about="urn:mimetype:handler:application/pdf"
NC:alwaysAsk="true"
NC:saveToDisk="true">
<NC:externalApplication RDF:resource="urn:mimetype:externalApplication:application/pdf"/>
</RDF:Description>
Become: <RDF:Description RDF:about="urn:mimetype:handler:application/pdf" NC:handleInternal="true" NC:alwaysAsk="false" />
Does it help if you also set some prefs via a user.js file in the \browser\defaults\profile location?
user_pref("pdfjs.disabled", true);
user_pref("plugin.state.nppdf", 2);
Such pref settings are also possible via a mozilla.cfg file.
These functions can be used in the mozilla.cfg file:
defaultPref(); // set new default value pref(); // set pref, allow changes in current session lockPref(); // lock pref, disallow changes

I found that, in the user profile:
-If I delete only "mimeTypes.rdf", mimeTypes.rdf get replaced by a correct version at the next launch.
-If I delete "mimeTypes.rdf" AND "prefs.js", mimeTypes.rdf is somehow replaced and modified at the next launch.
cor-el, sadly, no. But I think you're on to something, the answer lie in prefs.js I think.
It works for me with both the user.js file and your mimeTypes.rdf file.
user_pref("pdfjs.disabled", true);
user_pref("plugin.state.nppdf", 2);
<?xml version="1.0"?> <RDF:RDF xmlns:NC="http://home.netscape.com/NC-rdf#" xmlns:RDF="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <RDF:Description RDF:about="urn:mimetype:handler:application/pdf" NC:alwaysAsk="true" NC:saveToDisk="true"> <NC:externalApplication RDF:resource="urn:mimetype:externalApplication:application/pdf"/> </RDF:Description> </RDF:RDF>
It works cor-el .
Tears of joy.
I had to do a "locked_pref("plugin.state.nppdf", 0);" in user.js in "browser\defaults\profile" in my case.
Thanks a lot man.
So I confirm, you can deploy firefox with default external pdf handler.
