You are using the 32bit version of Firefox. Forum software detects you user agent string as
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
WOW64 indicates it is 32bit on a 64bit machine. The 32 bit version is normal for Windows users.
There is now a 64bit version available but that is not offered by default and will restrict the plugins you will be able to use.
- See Firefox 64-bit for Windows Available https://blog.mozilla.org/futurereleases/2015/12/15/firefox-64-bit-for-windows-available/
The information can be seen from the troubleshooting information page
Keying into the addressbar about:support is the quick method of getting that.

Windows users downloading from www.mozilla.org will get the 32-bit Firefox so if you want the 64-bit (Win64) Firefox go to the Systems &Languages link below in the green download box which is www.mozila.org/firefox/all/
To run Win64 Firefox you need 64-bit Windows 7, 8 (8.1), 10.
