I've uploaded the new version which supported IE8+.
https://www.absolute.co.th/app/test_ie8.htmlAnd the page which commented the code "chart.draw()"
https://www.absolute.co.th/app/test_comment_chart-draw.htmlYou can see that if you open test_ie8.html on FF, you will see that the page is not fully encrypted. But if you open the page test_comment_chart-draw.html, you will see that the page is fully encrypted.
So, I think that this may be not relate to the issue about google.load or script importing. Because, all scripts are loaded successfully before calling "chart.draw()" and the SSL connection is normal. But if chart.draw() is called, the SSL connection in FF will be flaw. I think this issue might be relate to chart rendering on FF.
