Indeed, there is a sizable set 32-bit Windows users.  The following is 
likely a fair estimate of our WINDOWS user population via crash 
statistics.   The numbers are percentage of users, and virtual memory 
size of the Thunderbird process.

All Thunderbird versions, all Windows versions

85.61 %  4294836224              32bit Thunderbird running in 64bit Windows
12.44 %  2147352576              32bit Thunderbird  running in 32bit 
Windows or 64bit Windows configured to run TB in 32bit mode
   1.43 %  140737488224256   64bit Thunderbird running in 64bit Windows

The subset of XP users is  0.07 %  or XP 5.1.2600 Service Pack 3

Windows 10 users only

93.44 %  4294836224                32bit Thunderbird running in 64bit 
Windows
    4.11 %  2147352576   **         32bit Thunderbird  running in 32bit 
Windows or 64bit Windows configured to run TB in 32bit mode
    2.30 %  140737488224256     64bit Thunderbird running in 64bit Windows
