When I get on my desktop and go to my Homepage( xfinity) and I try to pull up my email or other options I get a notice that "this page is slowing down Firefox.Please stop this page. And there is a little stop button. When I push the buttton It all works. I tried to fix the problem on your trouble shooting page and I made it worse. Now my home page doesn't show up in my toolbar. I'm 75 and not very computer savoy. Please help. Thanks.
