Disable or configure PDF.js, the built-in PDF viewer.
`Status` can be "default", "locked", "user" or "clear"
-Default preferences can be modified by the user.

+* `"locked"`: Read-Only: Settings appear as default even if factory default differs.

+* `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
-User preferences persist across invocations of Firefox. It is the equivalent of a user setting the preference. They are most useful when a preference is needed very early in startup so it can't be set as default by policy. An example of this is ```toolkit.legacyUserProfileCustomizations.stylesheets```.
