I was a Chrome user until like maybe 1 year ago. I kept away from Firefox because at the time it was very sticky and it seemed to use alot of resources, while chrome felt more sleek. From 3.5 (i think) mozilla stated that they had reduced resource usage so i thought i'd give it a try. Indeed it now runs way better than in the old times. Last time i tested it seemed Chrome would use more resources on multiple tabs while Mozilla seemed to perform a bit better. This is a very empiric statement and i'm no expert, that's why i ask you. So who do you think is better at this very moment?
