Prevent auto migration to 64-bit

Hey, I prefer to run Firefox 32-bit even though I use it on Windows 10 64-bit. I've made the switch a few times now and it keeps sneaking back to 64-bit. Is there a way to permanently disable or prevent Firefox from automatically upgrading me to 64-bit?

I did read a thread that said starting with version 56.0.1 it will no longer do the auto migrate but I would like to have a way to set it permanently just in case future updates change the auto migration rule.

Any thoughts or suggestions will be greatly appreciated.

I think that this was only a one time migration for users that have been using Firefox for a long time and started with a 32-bit Firefox version or at a time there wasn't a 64-bit Firefox version for Windows.

Note that Firefox 56.0.2 has been released, so please update.
