// "Section" : Description of the settings section separated by "----" |
// "Pref" : Preference/Settings name and or description followed by links or documentations |
// and some time explanation why the setting is commented and ignored. |
// "lockPref" : Locked preference can not be changed on firefox, nor by extensions, can only be changed here |
// lockPref is used to lock preferences so they cannot be changed through the GUI or about:config. |
// In many cases the GUI will change to reflect this, graying out or removing options. Appears |
// in about:config as "locked". Some config items require lockPref to be set, such as app.update.enabled. |
// It will not work if it set with just pref. |
// "pref" : Sets the preference as if a user had set it, every time you start the browser. So users can make changes, |
// but they will be erased on restart. If you set a particular preference this way, |
// it shows up in about:config as "user set". |
// "defaultPref" : Defaulting : Is used to alter the default value, though users can set it normally and their changes will |
// be saved between sessions. If preferences are reset to default through the GUI or some other method, |
// this is what they will go back to. Appears in about:config as "default". |
// "clearPref" : Can be used to "blank" certain preferences. This can be useful e.g. to disable functions |
// that rely on comparing version numbers. |
