Site Studio Contributor not opening in firefox

Question

I am trying to open site studio contributor form in firefox and its not opening.
As soon as I clicked Shift+Ctrl+F5, on webpage, it asks me for login credentials, after sucessull login, i am not getting any option (icon) to edit region defination etc
Before entering into site studio contributor entries are like:
var _U = "undefined";
var g_HttpRelativeWebRoot = "/idc/";
var SSContributor = false;
var SSForceContributor = false;
var SSHideContributorUI = false;
After going into contributor entries are like:
var _U = "undefined";
var g_HttpRelativeWebRoot = "/idc/";
var SSContributor = true;
var SSForceContributor = false;
var SSHideContributorUI = false;
I am using site studio designer (Version 10gR4 10.1.4.5.0 and component version 7.7.0.1 Build 9.0.0.470).
Please provide if you have any solution or information to fix the issue, I have tried the using different systems/machines having firefox, but facing the same problem

Answer 1

This seems to be covered by the support note 1465975.1 (Unable to Enter into Site Studio Contribution Mode After Upgrading to Firefox 13)
The solution from the note:
If on an 10g system upgrade to Site Studio 10gR4 build 9.0.0.793 or greater.
If on an 11g system upgrade to Site Studio 11g build 11.0.0.786 or greater. For example the 11g MLR 11 for a .6 system has this fix and the 11g MLR 18 for a .5 system has this fix.
If the version is not available with the current patchset on the 10g Content Server please open a new Service Request with Oracle Support and reference this Note ID and the build will be provided.
(there are few more notes with similar issues, in case this remedy won't help, but it'll do no harm to start with it either way)
