Actual results: The following message was displayed: Error: A script from "file://" was denied UniversalXPConnect privileges. Expected results: A dialogue box should have been displayed asking if I wanted to grant the privilege, as it does with Firefox 14 (and earlier). Comment 1 Benjamin Smedberg [:bsmedberg] 2012-09-13 05:56:55 PDT enablePrivilege is being completely removed from the platform. Comment 2 Angelo Borsotti 2012-09-13 12:55:32 PDT It is as if it had already been removed since there is no way to make it grant the privilege. What is then the replacement? Comment 3 Boris Zbarsky [:bz] (still a bit busy) 2012-09-13 13:00:00 PDT In Firefox 15 you can grant privileges in some cases by manually setting preferences. In Firefox 17, I believe that has been removed too. The replacement is to write an extension if you need to run privileged code. Comment 4 Angelo Borsotti 2012-09-13 15:01:02

Doesn't mozilla has any similar interfaces which can be implemented in the XPCOM component ?

Now I have changed my approach. Instead of modifying pref.js file, I am accessing the file from local folder. Can you suggest any way using which I can avoid the Warning dialog as well. I have tried adding the following to pref.js but it still not working.user_pref("capability.principal.codebase.p0.granted", "UniversalXPConnect");user_pref("capability.principal.codebase.p0.id", "f

Normally these are the causes that some program - for protecction purposes - blocks RPC javascript calls. -------------------------------------------------OpenKM Team ( be open my friend )http://www.openkm.com Top david Fresh Boarder Posts: 11 Joined: Tue Dec 16, 2008 11:52 am Re:UniversalXPConnect privileges denied Quote Postby david » Tue Dec 16, 2008 4:13 pm No, I haven\'t any plug-ins.
