1342347 - Revert stub installer default from 64-bit to 32-bit on Aurora 54

Status: RESOLVED FIXED

(Firefox :: Installer, defect, P1)

Description

[Chris Peterson [:cpeterson]]

+++ This bug was initially created as a clone of Bug #1338583 +++

We must postpone our 64-bit rollout again, now from Firefox 54 to 55 because Farmville 2 will be broken on 64-bit without async drawing (bug 1317995), but we can't enable async drawing until bug 1323403 and bug 1336517 are fixed. So we must revert 54's stub installer default from 64-bit to 32-bit.

Let's wait until 54 is in Aurora so we don't need to change the installer default back to 64-bit in Nightly 55.

This patch is identical to bug 1338583, just rebased for current aurora (and re-tested manually), so carrying over r+. I'll also copy over the same uplift request. As before, note that this patch is not intended to land in nightly 55, only aurora 54.

32bit by default for 54 stub installer

Looking forward to 55 when we can hopefully go 64bit finally :)
