How can I get URLs of open pages from Chrome and Firefox?

by

It’s specific for every browser. That’s for the major ones:

  • Internet Explorer – You can use SHDocVw (like you did)
  • Firefox – You can get the URL using DDE (source below)
  • Chrome – You can get the URL while enumerating all the child windows untill you get to the control with class “Chrome_OmniboxView” and then get the text using GetWindowText
  • Opera – You can use the same thing as Firefox, but with “opera”
  • Safari – There is no known method since it uses custom drawn controls

EDIT: Since 2014, Chrome has changed and you need to get the URL with Acessibility.

Code to get the URL from Firefox/Opera using DDE (which used NDDE – the only good DDE wrapper for .NET):

//
// usage: GetBrowserURL("opera") or GetBrowserURL("firefox")
//

private string GetBrowserURL(string browser) {
    try {
        DdeClient dde = new DdeClient(browser, "WWW_GetWindowInfo");
        dde.Connect();
        string url = dde.Request("URL", int.MaxValue);
        string[] text = url.Split(new string[] { "\",\"" }, StringSplitOptions.RemoveEmptyEntries);
        dde.Disconnect();
        return text[0].Substring(1);
    } catch {
        return null;
    }
}
