Firefox with me is the best one. Firefox is so open to a lot of add-ons and basically converting it to becoming something that is a personal browser. Google Chrome to me is a bit limited especially when he comes to mobile products for example YouTube. Also I find it a bit too personal and I feel that Google just collects a bit too much information when you're using chrome. So for me Firefox is that good and decent balance between a great browser and one that allows you to tweak it in whatever ways that you want
