Google’s entry into the browser space raised the question of the future of Mozilla. Mozilla is so far doing very well. But the question is really who will occupy the mobile set-top. That will decide the winner, at least in the short term.
The rise of Firefox unleashed a new wave of innovation and competition among browser makers. Microsoft and Apple, which makes the Safari browser, have narrowed the gap with recent upgrades. That makes it less likely that people will take the trouble to seek out and install Firefox.
At the same time, the Web has been migrating from PCs to powerful mobile phones like the iPhone. Firefox won’t have a mobile version ready until later this year.
