Description

Attachment: errorprivileges.html

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:14.0) Gecko/20100101 Firefox/14.0.1
Build ID: 20120713134347

Steps to reproduce:

Opened a page that contains javascript and that works fine with
Firefox 14, but does not with Firefox 15.


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]

enablePrivilege is being completely removed from the platform.

Comment 2

[Angelo Borsotti]

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

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]

I set manually the preferences by adding to the prefs.js file
(in the profile directory) the appropriate lines, but have
got the same error message.

Hence "in some cases".  For file:// URIs there are some ... issues, as I recall.
