It certainly did not ask for me and just switched from startpage to Google. Also auto-installed the update (against my will) after I had voted to wait a few times, though that might have been autoupdate as it was on my work computer (have heard from others that it was not which I also suspect but I am too lazy to check). Mozilla is certainly losing trust with that, if it weren't for the lack of good alternatives...
There is a good alternative called waterfox (yup the name says it all) and of the recent update disabled the dreaded auto update thing trying actively to get rid of your legacy extensions.
