Question

I have a windows applicaiton c# catching the url of a running firefox instance.
I have always used “MozillaContentWindow” to get firefox URL but i dont understand why it dont work anymore.

string s = GetUrlFromBrowsersWithIdentifier("MozillaContentWindow", foreGround);

public string GetUrlFromBrowsersWithIdentifier(string identifier, int foreground)
    {
        try
        {
            IntPtr ptr = new IntPtr(foreground);
            var aeBrowser = AutomationElement.FromHandle(ptr);
            return aeBrowser == null ? "" : GetURLfromBrowser(aeBrowser, identifier);
        }
        catch (Exception ex)
        {
            return "";
        }
    }

    string GetURLfromBrowser(AutomationElement rootElement, string identifier)
    {
        try
        {

            Condition condition1 = new PropertyCondition(AutomationElement.IsContentElementProperty, true);

            Condition condition2 = new PropertyCondition(AutomationElement.ClassNameProperty, identifier);

            var walker = new TreeWalker(new AndCondition(condition1, condition2));

            var elementNode = walker.GetFirstChild(rootElement);

            if (elementNode != null)
            {
                var p = elementNode.GetSupportedPatterns();

                if (p.Any(autop => autop.ProgrammaticName.Equals("ValuePatternIdentifiers.Pattern")))
                {
                    var valuePattern = elementNode.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;

                    if (valuePattern != null)
                        return (valuePattern.Current.Value);
                }
            }
        }
        catch
        {
            return "";
        }

        return "";

    }

Now when it enters “walker.GetFirstChild(rootElement);” it just stops there. I cant figure out why. This only happend on latest version of firefox.

Did they change the name of the value bar containing the url?

Thank you

Try using MozillaWindowContentClass for newer versions.
