This fix prevents the website editor from failing in Firefox when it encounters stylesheets from another domain. Same-domain styles continue to work normally, while restricted external styles are safely skipped so users can keep editing without disruption.

…cssRules, it is due to Cross domain security policy of firefox, used try catch, so that if there is cross domain css then skip it, it should not break the system, atleast it should work for same domain css, cross domain css should skipped
