The problem developed 11/26. When I navigate thru ebay to list and item for sale I am taken to a page to choose the category. I select the category and click continue. This brings me back to the previous page and in red tells me to select a category. I select the category and click continue ad it brings back to the previous page and is highlighted in red to choose a category. I cannot navigate past this page. It is only on my computer. My son does not have the issue on his computer, but if he signs onto ebay on y computer he has the same issue. Using Safari as a browser there is NO problem and I am abe to navigate and list as I have previously done through Fire Fox before the problem began today
