Firefox throws table off page to right , other browsers fine

Here is a page that has been made responsive, and works fine in Chrome, IE, Safari but not Firefox.
For Firefox the table gets thrown off the page to the right on all devices including desktop. Any ideas why?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Also not working for me. This is a problem with the Website. Tested on 5 Clients.

<span class="clear"></span> needs to be replaced with <br clear="all">.  'span' is not a 'block' element and I can't find the 'clear' class.  It works correctly in Chrome with that change also.

Excellent that works thank you. This was a template written some time ago by a well regarded programmer.   I would never have found it, so appreciate your help.

You're welcome.  Glad to help.  It probably worked when he wrote it.  Browser interpretations sometimes change in the details they will accept.
