Some pages has been loaded really slow down because
there is some problem with permission to using call method UnnamedClass.toString.

Error reports:

Error: Permission denied for <http://www.facebook.com> (document.domain=<http://facebook.com>) to call method UnnamedClass.toString on <> (document.domain has not been set).

Error: uncaught exception: unknown (can't convert to string)
Error: Permission denied for <http://www.facebook.com> (document.domain=<http://facebook.com>) to call method UnnamedClass.toString on <> (document.domain has not been set).

1.Open some page with unknown string, for example http://facebook.com
2.Page has been loaded very slow(i compared this issue with other browser IE8,chrome 7, safari)
3.Check error logs in firefox
Actual Results:  
Page is loaded very slow

Expected Results:

This could be caused by an extension, for example. There's nothing in your report that indicates that slow loading is *caused* by the same thing that caused the error in the console.
