Open your Windows Forms designer, and drag a GeckoWebBrowser control from the toolbox onto your form. Once the control is on your form, you can set properties like Dock to Fill to make it fill the entire form, or set Anchor to resize with the form.

Adding the below line to your constructor.

Xpcom.Initialize("Firefox");

Adding a load event handler to your form allows you to navigate to the url. You can load web content into the GeckoWebBrowser control using its Navigate() method.

private void frmGeckofxBrowser_Load(object sender, EventArgs e)
{
    txtUrl.Text = "https://foxlearn.com";
    geckoWebBrowser1.Navigate(txtUrl.Text);
}

Adding a keypress event handler to the TextBox control allows you to enter key, then navigate to the url.

private void txtUrl_KeyPress(object sender, KeyPressEventArgs e)
{
    if (e.KeyChar == (char)13)
        geckoWebBrowser1.Navigate(txtUrl.Text);
}
