When I was much younger I used to use Netscape (oh those glorious early internet days...).
I remember Mosaic when it was launched. That changed everything and brought the much hyped world wide web to the masses. With Mosaic it became clear that this was superior to gopher. I did switch from Mosaic to Netscape when Netscape came out. Then I moved to Opera, then to Mozilla, and now I'm on Chrome. Browsers have become monsters eating gigabytes of memory for breakfast, which was why I moved from Mozilla to Chrome, but Chrome is pretty bad too.
