Hey guys, I have a late 2009 iMac with 12GBs of ram, running OSX Mavericks and I am having a problem with firefox. HTML5 (I assume its HTML5) based websites are running quite sluggish, for example www.gamespot.com is every so choppy when I scroll, compared to Safari where its buttery smooth. I have disabled hardware acceleration and smooth mouse scrolling to see if this fixes the problem and it has had no effect what so ever. I am a new firefox adopter, I find it to be the browser that works best for my needs but unfortunately this problem is really making it quite irritating to use. Does anyone have any idea on what the problem could be? Thanks guys.
