Is this about replacing one monopoly with another? It is slowly starting too look like in the early 00's, most developers are starting to support only chrome, with no testing in Firefox or latest IE. On Android it is even worse, no one is testing with Firefox Mobile (Fennec) - this is WinXP-IE6 all over again.
What I don't understand about Firefox is that Mozilla have a lot of money but progress seems very slow. Sure they get there in the end (or most of the way) but it just seems to take forever. Why?
