Your user agent in more system details on right of your post shows this.

Mozilla/5.0 (Windows NT 6.0; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0.1

Note the WOW64 as this means it is a 32-bit app running on 64-bit Windows.

Mozilla does not have 64-bit Firefox releases for Windows yet while there has been 64-bit builds for Mac OSX and Linux since Firefox 4.0
