Got it working.

Solution:
Code:
        private void Form1_Load(object sender, EventArgs e)
        {
            Settings1 set = new Settings1();
            string url = set.home;
            Uri uri = new Uri(url);
            ArrayList a = new ArrayList();
            for (int i = 0; i <= tabControl1.TabCount - 1; i++)
            {
                WebBrowser web = new WebBrowser();
                web.Size = tabControl1.TabPages[i].Size;
                web.Url = uri;
                web.Name = "Webbrowser"+i.ToString();
                tabControl1.TabPages[i].Controls.Add(web);
                a.Add(web);
            }
            foreach (Control c in a)
            {
                if (c is WebBrowser)
                {
                    WebBrowser brow = (WebBrowser)c;
                    brow.DocumentCompleted += browser_DocumentCompleted;
                }
            }
        }


        private void browser_DocumentCompleted(object sender, EventArgs e)
        {
            WebBrowser brows = (WebBrowser)sender;
            brows.Parent.Text = brows.Document.Title;
        }
