I'm ex firefox user but now I'm all Chrome. I just love the simplicity and minimalistic design. Go Chrome!
I installed both of them. Chrome is faster and lighter than Firefox, but I still prefer the firefox because of its functionality
Both browsers are good to use. For me its Mozilla Firefox just because i can use so many addons with that. DON.
I use both simultaneosly for different sites. For example, I use Google Chrome to browse sites owned/operated by Google such as YouTube, GMail, Google Docs, etc... They're both amazing at what they do but I simply can not choose one.
At first i was using firefox, then after some time i shifted to chrome but it failed for me, so i returned back to firefox
I actually use Chrome most of the time these days. Chrome not perfect but its easy to use and very fast.
Chrome is lightening fast, but it lacks some features like toolbars, plugins etc. i am sure it will get included in forthcoming updates.
I use FireFox just because of plugins. I won't use Chrome because I don't like the idea of Google taking over the entire internet world one day.
