Is it possible to create a default
mimeTypes.rdf file for all the existing and new users ?
So that whenever a user opens the firefox for the very first time, he will get the specified rdf file in his profile @
If you are creating users with
useradd you can file directory
/etc/skel to put files and directories in users home directories.
man useradd: The skeleton directory, which contains files and directories to be copied in the users home directory, when the home directory is created by useradd.
So you should create two files:
/etc/skel/.mozilla/firefox/PROFILE_NAME/mimeTypes.rdfwith content that you need
[General] StartWithLastProfile=1 [Profile0] Name=Default User IsRelative=1 Path=PROFILE_NAME Default=1
It should do the work with new users.
I found occurrences of
/usr/lib/firefox/defaults/profile/mimeTypes.rdf on the web, but I'm not sure it will be used by recent versions of firefox. Might be worth a try!
