We must postpone our 64-bit rollout from Firefox 53 to 54 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 53's stub installer default from 64-bit to 32-bit. Romain will ask Bryan Clark if we should revert in Aurora 53 or whether we can wait until Beta 53 (so we get more Aurora users testing 64-bit, even though we know it has some Flash bugs).
Given the low number of new users on Aurora when compared to the existing Win64 population on Aurora, keeping Win64 as default won't bring much testing value and the right approach is to avoid known bugs on Aurora. Bryan agrees, let's revert the stub default from 64 to 32 bit until the async drawing issue is fixed.
@ Romain: thanks for discussing with Bryan. I agree we should revert the installer default on Aurora. One might make the same argument for Nightly until we fix the async drawing bugs, but I don't think we should change Nightly installer's default for now. @ Matt: can you please post a patch to change the 53 stub installer's default architecture from 32-bit to 64-bit?
Status: NEW → ASSIGNED
This patch disables 64-bit as the default for new installs, but leaves the option in place to select it manually.
