I used Mozilla Firefox for years.
I'm still remembering the first version which I used was 3.0 - So smoother, faster, better than IE6 and Opera. And yes, the legend tagline “Take back the web”, too! Without Firefox, I didn't get a step into Web 2.0 and Open Web Standards.
At this time, my laptop are running version 79.0. Hope Firefox will get a 100th Anniversary
