|There is an online game which I've always played and it requires some rapid refreshing but for the past couple of days each of my browsers have had problems doing that. They lag, the page goes white or freezes altogether.|
IE 7/8 (actually, this has always been bad :P), Firefox, Opera, Orca, Safari, Google Chrome... all the same. Firefox is the worst though and is the browser I normally use to play.
With Firefox I've tried upgrading to the latest, downgrading to a version that worked really well and disabling add ons but nothing has helped.
