Although Firefox 37 is already released, I still can't update (still stuck in Firefox 36.0.4). When I see the window "About Firefox" a message that my browser is updated appears. I downloaded the setup file of Firefox 37. I installed it as I always do and when opening Firefox, a failure occurs and this unexpectedly quits. I don't understand because my Firefox doesn't detect the update. I even tried to do a clean install (not upgrade) and still the problem of "unexpected shutdown" is happening.
