GetComputedStyleValue() does not work in FireFox

[Toldo]

Hello,

When I am using next code to get computed CSS style value it works in every browser except FireFox (v.14.0.1 and v.15.0):

string style = new HtmlControl(element).GetComputedStyleValue("font-family");

I have managed to proceed with workaround in JS, but it looks like something wrong with plugin in latest FF browser versions.

string script = @"function getstyle() {var el = document.getElementById('" + element.IdAttributeValue + "');" +
"var computedStyles = window.getComputedStyle(el, null);\n" +
"return computedStyles.getPropertyValue('font-family')}\n getstyle()";
style = Actions.InvokeScript<string>(script);

The exception thrown listed below:

ArtOfTest.WebAii.Exceptions.ExecuteCommandException was unhandled by user code
