When I try Firefox or IE with your site it does show your site name. Its based on the meta tag that gets added to the page and that does have your site name.
<link rel="search" type="application/opensearchdescription+xml" title="i7MEDIA - Creative Web Solutions Site Search" href="http://i7media.net/SearchEngineInfo.ashx" />
If it somehow got cached in your browser as mojoPortal I'm not sure if clearing the cache will solve it or not.
Hope it helps,
