23.0 r0 In Firefox And Your Site

I am running Windows 64-Bit.  Now that there is an update, how am I supposed to test for my version in Firefox?  The box that is supposed to show the installed version shows up as black on this page:  http://www.adobe.com/software/flash/about/  In SeaMonkey I only had to click on the black area and it eventually showed the version.  I installed the update first in IE11.
