On a Windows 7 computer, My Firefox network.proxy.type is locked so I cannot modify it When looking at C:\Program Files (x86)\Mozilla Firefox\default/prefs/localsettings.js there are only 2 lines:
Then when looking at config.cfg there is no line looking like
and when I try to add my own preference with an other value
pref("network.proxy.type", 2); I see in firefox that the preference is locked and don't take my value in account.
I also looked inside about:support to determine my profile directory and looked in every .cfg and .js files but still no lockPref that could explain why network.proxy.type is locked
Is there a way to know from which configuration file the lock is coming ? During my web search I found a lot of pages explaining how to lock some options etc but nothing on how to understand why an option is locked
Thanks by advance for your help
