Cannot edit my created team.

I was able to edit my teams on team builder yesterday. It took forever to create a team because I could only make one change and then the page would stop responding. This happened in all of the sections. (IE Uniforms, Stadium, etc.. I would have to reload the page and that resulted in being taken back to the home page get started page. I would go back to edit changing one thing and then save. The page would stop responding again. Rinse and repeat for hours. Finally, I got everything done and ready to submit. I had issues with the stadium section when trying to click on numbers 50 and 20 yd line were not responding at all. Could not click it.  It was late, so I was going to wait until the next day. Now when I click get started, my team, edit my team, it will not load my team. So I reloaded the page and was sent back to the start page. Went to edit again, and then it just sent me back to the start screen. Now I cannot even get into my teams I have made. It just continually sends me back to the start page without even going to the edit page. I'm using Firefox and no other browser will work.

Very Frustrated,
