I would love to continue using FF, but on my machine with an Nvidia card (sigh) the scrolling in Firefox gets very choppy when using two different browser windows open on the dual monitors. And for some reason this bothers me more than it should. Maybe one of these days I should try using it again. It's been over a year since I last tried it. It's odd because the Firefox on the desktop machine with the Nvidia card and a six core AMD CPU is way choppier than on my 7 year old Thinkpad with a dual core i5 and integrated graphics.
