Are there any tech head sellers out there who can help me with why I get this message repeatedly when I try to do listing straight from the Ebay sell an item tab?

I do the whole listing and then go to continue or save for later and get this message: -

The connection was reset

The connection to the server was reset while the page was loading.

The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

All the info I put in is lost and the uploaded photos dissapear.

I have deleted cookies, cleared the cache, tried different browsers  - all with the same result.

 No problem with any other web pages either - just good old ebay. I can also load other pages on ebay.

It is very frustrating - I have been trying to do a listing for the past hour and have all but given up!
