I use chrome BUT Firefox is better. Its just a fact.
Chrome looks more beautiful, it loads faster if you enable the pre-cache thingy but it also doesn't delete the cache memory on the go which can create some browsing problems.
I can't really use IE because I use linux, and when I did use IE it was the shittiest browser I had used. So many problems its not even funny. Opera to me is much better than IE, and is very very good, just not as good as Firefox or Chrome.
And I am totally not getting all the fear of google on this thread. Google, as I see is a very friendly corporation. At least to the consumers. Their service is fantastic.
