I am using following jquery function in Firefox Mozila.

jQuery.expr[':'].containsNoCase = function(el, i, m) {

var search = m[3];

if (!search) return false;

return eval('/' + search + '/i').test($(el).text());

};

Below is the error message I can see using Firebug.

Error: Syntax error, unrecognized expression: unsupported pseudo: containsNoCase

throw new Error( "Syntax error, unrecognized expression: " + msg );
