The included wow_helper.exe is 64-bit, but I use the 32-bit of Firefox

Browser: Firefox v44.0.1 (32-bit, Windows) OS: Microsoft Windows XP Professional SP3

I noticed in Firefox v44.0.1 (32-bit, Windows) that the included wow_helper.exe is a 64-bit application. Is this a mistake for 32-bit Windows operating systems?

I found a Bug report that gives somewhat of an explanation with that binary is used for in 32-bit Firefox. https://bugzilla.mozilla.org/show_bug.cgi?id=1160514#c20

"Confusingly, this is for win32 builds, so it does affect beta and release. At least for Vista 64-bit and WinXP 64-bit (64-bit OS and 32-bit Firefox that is).

The 64-bit wow-helper.exe binary is needed for some of the process memory patching that happens during the sandbox launch, when the 32-bit plugin-container.exe is running under WOW64."
