There is'nt a buitin way to watch for hash changes, in firefox you could use watch method, but as far as I know it isnt default, so you can hack it writing something like (see below)

function setWatchHashChanges(functionObject)
{
    if(window.location.watch)
    {
        window.location.watch('hash', function(e){functionObject(e);return e;});
    } else {
        if(!setWatchHasnChanges.hash)
        {
            setWatchHasnChanges.hash = window.locaton.hash;
        } else {
            setInterval(function(){
            if(setWatchHasnChanges.hash!== window.locaton.hash)
            {
                setWatchHasnChanges.hash = window.locaton.hash;
                functionObject(setWatchHasnChanges.hash);
            }
        }, 100);
    }
}
