Firefox is developed by a company with hierarchies. Those other ones have the advantage of being very old and lots of time to iterate on them. Open source produces lots of gems, the problem is that it is very slow moving and IMO the effectiveness is cut in 10 by duplication of effort and lack of coordination. For every successful open source project, there are about 20 stubs and 5-10 less successful open source programs that do basically the same thing.
