I was unable to open Intellicast.com pages after upgrading from Firefox 11 to Firefox 12. IE will open the pages. I upgraded to FF 13 a couple of days ago, and was pleased to see that the site worked in that version. Alas ... it was only that first time. After that, the sites pages once again fail to load. Cleared the cache, trashed that domain's cookies, without improvement. No error messages appear ... the page merely loads ad nauseum, with no data displayed.
