Status: RESOLVED DUPLICATE of bug 980023

(Add-on SDK Graveyard :: General, defect)

Description

[[e-mail]]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:29.0) Gecko/20100101 Firefox/29.0 (Beta/Release)
Build ID: 20140421221237

Steps to reproduce:

Our Add-on uses localStorage to store user data in website context. It access localStorage via injected content scripts using standard methods:

localStorage.getItem(key);
localStorage.setItem(key, value);

Code is injected to website via PageMod:

pageMod.PageMod({
            contentScriptFile: [
                self.data.url("app.js")
            ]})

Additional info:
We are using Addon SDK 1.16 
Problem occurs since FF 29.0 beta (everything works with FF 28)


Actual results:

When methods getItem/setItem are called, security exception is thrown: [Exception... "The operation is insecure."  code: "18" nsresult: "0x80530012 (SecurityError)"  location: "<unknown>"]


Expected results:

Value should be stored in (read from) local storage.

Might be related to the SDK, so I'm moving it there first.

I've landed a patch for this problem, it should be fixed in ff30.
