+++ 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.
Created attachment 8844981 [details] [diff] [review] Disable 64-bit as default for new installs 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. Approval Request Comment [Feature/Bug causing the regression]: See comment 0 [User impact if declined]: Misbehavior or outright failure of popular Flash applications [Is this code covered by automated tests?]: No [Has the fix been verified in Nightly?]: No, it's not intended for or needed on nightly [Needs manual test from QE? If yes, steps to reproduce]: No, I've tested it manually [List of other uplifts needed for the feature/fix]: None [Is the change risky?]: No [Why is the change risky/not risky?]: It's a very small and focused change, and I've manually verified it [String changes made/needed]: None
Comment on attachment 8844981 [details] [diff] [review] Disable 64-bit as default for new installs 32bit by default for 54 stub installer Looking forward to 55 when we can hopefully go 64bit finally :)
