It can be rightly said that, Mozilla and its leadership team is on the crossroads at the moment with Eich having resigned. All this has come down when Mozilla is in quite a tight spot. Firefox OS is not getting nowhere or atleast what it deserves. Chrome has become the new favorite browser of masses and is on the way to displace much-maligned IE from the throne. Thunderbird's development has become stalled. And things are definitely not looking for the reception of new Australis interface which is due for release in Firefox 29.
Even after his resignation, things are not looking good, as now the conservatives are now deriding Mozilla for handling this poorly. It would take Mozilla atleast some time to get out of this difficult phase.
