Mozilla Firefox (Portable) - Bundle 32-Bit and 64-Bit
Mozilla Firefox is detected correctly two times on my system (32-Bit and 64-Bit):
When you download this package from PortableApps.com then this package includes both versions (32-Bit and 64-Bit).
So here these two versions should also be bundled together.
Tell me if you need a screen shot or more information.
