Which sites are YOU not getting on?

IE8 and Firefox has no problem to me regarding those questions that you ask. But the pain is in the game stuffs. I always encounter lags in Firefox while playing social city and petville while IE8 doesn't. But in times on replying to chat window, some glitch was encountered while using IE8, but none in firefox. But sometimes I found more glitch on farmville while in IE8 than in firefox. I thought that it might on the browser's code handling in terms of executing javascripts, flash scripts, php, and others related on web programming codes.
