Greyed Page on Firefox

If I login to my site on Firefox I get a greyed/dimmed screen which is inaccessible, i.e. I cannot mouse-click on anything such as the edit button, the Dashboard button or any of the website functionality

Just Firefox, or have you tried chrome or IE? Can you click on to other Firefox tabs? You seem to be implying that it's a browser issue.
