I continually get this error message after Firefox updated. I am running FF 22.0. I updated Java, no joy in getting rid of the error messages, " evalInSandbox:Error: Permission denied for <https://facebook.com> to create wrapper for object of class UnnamedClass" & "Error: Permission denied for <https://facebook.com> to create wrapper for object of class UnnamedClass". It's something with the Javascript application. Any idea as to why these messages keep popping up & how do I fix this?

Thanks, Philipp. That appears to have solved the problem. I knew it had to have been one of the add ons, but I tried disabling them one by one and still got the error message. I may have missed that Social Fixer one, I don't recall.
