Best internet browser for playing games? Farmville.?

I play farmville..... (Yeah yeah i know... either the most loved or the most hated game on fb) :) Anyway. I started out with my ol' IE8 ... slow... went to firefox.. still slow. I am on roadrunner TWC service and everything else loads reasonably except farmville... I have tried disabling all my add on's... didn't help. I also added adblocker and set it up so that no animals or buildings ,(etc).. load. ( i have also run malware.. spyware, virus scans ..) Any ideas on what to do next? would switching browsers help. Thanks in advance
