Joomla! Template AGROnomy PT - Item Support

Please advise how to use the quickstart supplied with the template
I have been slowly building a site using Agronomy template and have found it easy to use, however today I was adjusting the iPhone template on my laptop and the site has now locked into the iPhone style only on Firefox and only on my laptop.
I have checked other browsers and other computers with Firefox and they are all OK.
On my machine the cpanel tab is missing and the iphone menu does not work so i can't seem to get out of the iPhone template.
Any advise please
Can anyone please help with the issue of being locked into the iPhone style on Firefox.
