Thoughts on 64-bit-only for Firefox Beta, Dev, Nightly and Thunderbird Beta
I recently switched the Google Chrome Portable Beta and Dev channels to 64-bit from 32-bit. I did this as it's currently not a dual mode 32-bit + 64-bit app due to the touchy launcher and portablization. I'm considering switching Firefox's Beta, Dev, and Nightly channels as well as Thunderbird's Beta channel to 64-bit only. It's currently a dual mode app, but I'm wagering than anyone wanting to test out upcoming features is probably not using an old Windows 32-bit machine. This would save on build and upload time.
