browser issue: "evalInSandbox:Error: Permission denied for <https://facebook.com> to create wrapper for object of class UnnamedClass "

Asked by Paul E. Meyers on 2013-10-21

Dear Tech Support,
     Due to some financial difficulties, I was without internet service for several months and when I got back on-line a few weeks ago, I was informed that the version of Ubuntu Linux I was using would no longer be receiving critical updates. I upgraded to the version offered and now my sound does not work. I checked all of the settings and connections and everything seems to be in order. I therefore believe that the problem occured during one of the updates I downloaded in the past couple of weeks since I upgraded my Ubuntu Linux.
     Also ever since I upgraded, I have been receiving these messages everytime I open a tab. [Javascript Application] appears in the header of the box. The first message is, evalInSandbox:Error: Permission denied for <https://facebook.com> to create wrapper for object of class UnnamedClass I click 'Okay' and the second message appears, Error: Permission denied for <https://facebook.com> to create wrapper for object of class UnnamedClass These messages will appear 2 and sometimes 3 times in a row before I can do anything on my computer.
     How can these difficulties be corrected? I have Ubuntu 12.04 LTS. I use an IBM Thinkcentre with an Intel Pentium processor 4cpu 2.04 GHz

My email address is <email address hidden>

Thank you for your assistance.

I assume you are using the "Social Fixer" browser extension in your browser.

Trying uninstalling this social fixer browser extension.

Then close all web browser instances and retest in a new browser window.

If issue still occurs after that, disable all other webbrowser extensions until you find the root cause.....

Please create a separate question for the sound issues, which is unrelated to the browser issue.

The rule here is "a separate thread per issue per user".
