Hello, I have an 21' iMac (4 gig Ram, 3.06 i3) with 10.6.8 and I use safari 5.1.2 (which I keep 'naked' and constantly reset it) and firefox 8.0.1 which i have bookmarks, pass-codes, ect and fasterfox lite on. My internet speed is about 40 mbps. Starcraft 2 runs fine ol, downloading is fine, my computer runs great actually...except the browser(s)... It doesn't matter what kind I use (chrome, opera included) my browsers are always sluggish and very inconstant. I cannot open any extra tabs and have to constantly quit the browser and reload. My iPad 1 and Iphone 4s browsers work faster and so does my friends older labtop as I have done comparisons. I've tried using an open DNS and creating another user profile nether helped. Any hints would be helpful.
