I love the direction Firefox has taken lately. I am using Firefox as my daily browser, as well as main developer browser. It feels right. I did use Chrome until fairly recently, but switching back to my favorite browser was a good call!
I certainly think that Firefox has the possibility to take back a lot of the lost market shares. I also hope so for the sake of the web. Mozilla is doing so much good for us all, and I for one appreciate it immensely.
