Why does Firefox set network.protocol-handler.expose.(protocol) to "true" on every start?
I want to make FF open "file://"-links with the Windows Explorer. It works if I set "network.protocol-handler.expose.file" to false and "network.protocol-handler.external.file" to true. But "network.protocol-handler.expose.file" is missing in about:config after a restart. So i've set it in my user.js. Now I can see the variable but its always set to true no matter what stands in my user.js. Why is FF overriding my config?

thank you
That should be OK.
Firefox should store the protocol settings in the mimeTypes.rdf file.
