Chart on firefox 5.0

Hi,
Hi, I just upgraded my Firefox browser to version 5.0 and I can not see the graphs that previously worked.
The error displayed is:

Error: Uncaught exception: [Exception … “Operation is not supported” code: “9” nsresult: “0x80530009 (NS_ERROR_DOM_NOT_SUPPORTED_ERR)” location: “dhtmlxChart/codebase/dhtmlxchart.js Line: 130”]

This is the script I use:

var data = [
{Minuti: “12465,91”, Servizio: “aaa”},
{Minuti: “17640,54”, Servizio: “bbb”},
{Minuti: “2611,49”, Servizio: “ccc”},
];

var barChart1 = new dhtmlXChart({
    view: "bar",
    container: "chartbox",
    value: "#Minuti#",
    label: "#Servizio#",
    width: 30,
    gradient: true,
    border: false,
	xAxis: {
        title: "Servizio",
        template: "|",
    },
    yAxis: {
        title: "Minuti",
    }
});
barChart1.parse(data, "json");

Anyone knows the problem?

I found a post that shows a problem similar to mine:

viewtopic.php?f=8&t=19111

but replaced dhtmlxchart.js and dhtmlxchart.css with those found in the post (chart.zip files) I get the following error:

Error: Uncaught exception: [Exception … “Operation is not supported” code: “9” nsresult: “0x80530009 (NS_ERROR_DOM_NOT_SUPPORTED_ERR)” location: “dhtmlxChart/codebase/dhtmlxchart.js Line: 4809”]

Values should be in a correct JS format. Please use . as a float delimiter:

var data = [
{Minuti: “12465.91”, Servizio: “aaa”},
{Minuti: “17640.54”, Servizio: “bbb”},
{Minuti: “2611.49”, Servizio: “ccc”}
];

Ok, it works
I had not seen the error
thanks
