Does anyone here only have a single browser installed on their computer? I always install Chrome, but do less than 0.1% of my browsing in it. What's the reason you couldn't have both? Storage? What you gain from using something other than Chrome is privacy, and using something other than Chromium makes it harder for Google to gain more control of the internet. That being said, I find both Firefox and Safari to be better experiences than Chrome.
